摘要： It is an object to provide a display device in which a problem of light leakage from a liquid crystal element in black display is reduced or overcome and the contrast is improved. It is another object to provide a pixel circuit having a function to control a lighting state of a backlight based on each pixel. These objects are achieved by turning off a light-emitting element in display of a black gray scale, and by providing a light-emitting element in each pixel and providing, in a pixel circuit, a function to individually control lighting and non-lighting of the light-emitting element depending on a gray scale to perform display. When a backlight is provided in each pixel, a light-emitting element that is a backlight is turned off when a black gray scale is displayed, whereby reduction in contrast due to light leakage from a liquid crystal element can be prevented.

摘要： Variations occur in the characteristics of transistors. The present invention is a signal-line drive circuit comprising first and second current source circuits corresponding to respective plurality of signal lines, a shift register, and n (n is a natural number of one or more) video-signal constant current source s, wherein each of the first and second current source circuits has a capacitance means and a supply means. The capacitance means held in one of the first and second source circuits converts a current including a current supplied from each of the n video-signal constant current source s to voltage in response to a sampling pulse supplied from the shift register and a latch pulse supplied from the exterior; and the supply means held in the other supplies a current responsive to the converted voltage. The values of the currents supplied from the n video-signal constant current source s are set to a proportion of 20:21: . . . :2n.

摘要： The inventors found out that in the case of performing a low gray scale display in which a very small amount of current is supplied to a light emitting element, variations in threshold voltages of driving transistors become notable since the gate-source voltage is low. In view of this, the invention provides a display device in which variations in the threshold voltages of the driving transistors are reduced even in the low gray scale display, and a driving method thereof. According to the invention, a gate-source voltage of the driving transistor is set higher in the low gray scale display than that in the high gray scale display. As one mode to achieve this, different power source lines are provided for the low gray scale display and the high gray scale display and their potentials are set to be different.

摘要： A source-drain voltage of one of two transistors connected in series becomes quite small in a set operation (write signal), thus the set operation is performed to the other transistor. In an output operation, two transistors operate as a multi-gate transistor, therefore, a current value can be small in the output operation. In other words, a current can be large in the set operation. Therefore, the set operation can be performed rapidly without being easily influenced by an intersection capacitance and a wiring resistance which are parasitic on a wiring and the like. Further, an influence of variations between adjacent ones can be small as one same transistor is used in the set operation and the output operation.
