摘要： A pixel electrode is configured of one comb tooth portion and a contact portion whose width is widened from the end portion of the comb tooth portion in a first direction that is the extending direction of a scanning line. The width of the contact portion is not expanded in a direction opposite to the first direction, and the production of a domain is prevented. A picture signal line is bent in the direction in which the width of the contact portion of the pixel electrode is widened, so that the comb tooth portion of the pixel electrode can be disposed in the center between the picture signal lines, and the width of the contact portion can be formed in a sufficient width in the direction in which the picture signal line is bent. Thus, the contact margin of the pixel electrode can be provided.

摘要： A liquid crystal display device has a pair of wall electrodes facing each other, which is disposed on pixels on a first substrate, functions as one of pixel electrodes and a common electrode, and takes a posture of standing on the first substrate. Also, the liquid crystal display device has a center electrode that is disposed between the pair of wall electrodes, functions as the other of the pixel electrodes and the common electrode, has a convexity lower in height than the pair of wall electrodes, and makes a width in a direction along which the pair of wall electrodes faces each other gradually smaller toward the second substrate. According to this liquid crystal display device, since a vertical electric field can be prevented from being developed on an upper side of the center electrode, a transmittance of light can be improved.

摘要： According to an aspect, a display device includes: a substrate; a plurality of pixels; a first anisotropic diffusion layer and a second anisotropic diffusion layer that are layered; and a plurality of light emitting elements interposed between the first anisotropic diffusion layer and the substrate. The first anisotropic diffusion layer and the second anisotropic diffusion layer each include a high refractive index region and a low refractive index region in a mixed manner. An absolute value of a first angle formed by a boundary between the high refractive index region and the low refractive index region of the first anisotropic diffusion layer and a direction perpendicular to the substrate is different from an absolute value of a second angle formed by a boundary between the high refractive index region and the low refractive index region of the second anisotropic diffusion layer and the direction perpendicular to the substrate.
