摘要： Disclosed is a single plate projection type display apparatus which is capable of achieving a high luminance without an increase in an output of a light source. A first lens plate having a plurality of lenses divides a light from a light source into a plurality of light beams. A second lens plate having a plurality of lenses superposes the divided plurality of light beams on a light valve, thereby performing an illumination. A color separation optical system composed of dichroic mirrors which are perpendicular to an XY plane and form predetermined angles to each other, performs a color separation for the light beams from the second lens plate. The light valve modulates R, G and B light beams which are incident thereonto. The modulated lights are projected by a projection lens. The whole shape of the second lens plate is a rectangle. The second lens plate is disposed so that a longitudinal direction of the longer side of the whole shape of the rectangle is perpendicular to a plane formed by a normal line to the dichroic mirrors and an optical axis immediately before an incidence onto the dichroic mirrors.

摘要： A front surface of the opposite electrode of a liquid crystal display panel is formed in a curved shape. The relation between the reflecting surface of the pixel electrode and the curved surface of the opposite substrate is defined so that a leaving direction of the light that is reflected by the first face of the opposite substrate is different from a leaving direction of light that is emitted from the first face of the opposite substrate after having been reflected by the pixel electrodes through the liquid crystal layer. Thus, undesired light on the front surface of the opposite substrate is separated from light that is displayed. Consequently, an image free of dazzling and deterioration of contrast ratio due to undesired reflected light can be obtained with a high contrast ratio. In a display apparatus containing the reflection type liquid crystal display, an incident surface to a dichroic prism is an inclined surface including a curved surface, not a surface that is perpendicular to the optical axis. Thus, signal light that is reflected on each reflection type liquid crystal display panel and that is displayed can be separated from undesired light that is reflected on the surface of the dichroic prism. Thus, an image with a high quality, and a high contrast ratio can be displayed.

摘要： A pixel electrode is disposed with an inclination angle to a base member on a front side (namely, an opposite substrate side) of a liquid crystal display panel. The relation between the reflecting surface of the pixel electrode and the main surface of the base member on the front side of the liquid crystal display panel is defined so that the difference between the reflecting angle of light that is entered as incident light and reflected on the surface of the base member and the leaving angle of light emitted as display light via the liquid crystal display panel exceeds the collection angle of the display apparatus. Thus, undesired light on the main surface of the base member of the display surface is separated from light that is displayed. Consequently, an image free of dazzling and deterioration of contrast ratio due to undesired reflected light can be obtained with a high contrast ratio. In a display apparatus containing the reflection type liquid crystal display, an incident surface to a dichroic prism is an inclined surface, not a surface that is perpendicular to the optical axis. Thus, signal light that is reflected on each reflection type liquid crystal display panel and that is displayed can be separated from undesired light that is reflected on the surface of the dichroic prism. Thus, an image with a high quality, and a high contrast ratio can be displayed.

摘要： When two substrates for a polymer-dispersed liquid crystal display panel are joined with a polymer-dispersed liquid crystal layer therebetween, a substrate supporting stage of a substrate joining machine is controlled to keep the uniformity in the screen of a space between the two substrates at a visually satisfactorily uniform level, thereby enabling to produce a liquid crystal display device provided with a polymer-dispersed liquid crystal layer having high uniformity in the screen. The above stage is preferably a transparent plate such as a quartz substrate. The transparent plate is used to uniformly and effectively irradiate the liquid crystal layer with ultraviolet rays to cure the liquid crystal layer by photo-setting. Besides, the two substrates having the polymer-dispersed liquid crystal layer therebetween are irradiated with light, interference fringes formed are observed, and a liquid crystal layer thickness value and the unevenness of the liquid crystal layer thickness can be detected based on the unbalance of a plane distribution and a density of the interference fringes. Based on the detected liquid crystal layer thickness value and unevenness of the liquid crystal layer thickness, the position and pressure of the supporting stage can be controlled to suppress the unevenness of the liquid crystal layer thickness and the variation of the pressure in the display screen to a level which does not effect on the reduction in display quality.

摘要： An object is to provide a liquid crystal display apparatus with an equal gap between two substrates so as to improve display image quality and display contrast. To accomplish this object, substrate gap adjusting region 33 or substrate gap adjusting layers 21, 22, 25, 27, 29, and 31 are formed so that the substrate gap in a region extending from a display region having pixel electrodes 7 to a driver circuit 11 is kept equal to the substrate gap in a region extending from the display region to a driver circuit 15. Thus, the gap between the two opposed substrates forming liquid crystal cells can be kept equal in any position.
