PURPOSE: An El display device and electronic apparatus are provided to realize an EL display device for displaying an image which has a good balance between the desired brightnesses of red, blue, and green light, using organic EL materials with different brightnesses of red, blue, and green light. CONSTITUTION: The EL display device has a pixel portion(101), and a data signal side driver circuit(102) and a gate signal side driver circuit(103) arranged in the periphery of the pixel portion, which are all composed of TFTs formed on a substrate. Note that although the EL display device has one data signal side driver circuit and one gate signal side driver circuit in the embodiment mode of the present invention, two data signal side driver circuits may also be used in the present invention. Furthermore, two gate signal side driver circuits may also be used. The data signal side driver circuit(102) fundamentally Contains a shift register(102a), a latch (A)(102b) and a latch (B)(102c). Further, clock pulses (CK) and start pulses (SP) are input to the shift register(102a), digital data signals are input to the latch (A)(102b), and latch signals are input to the latch (B)(102c). The digital data signals input to the pixel portion are formed by a time partitioning gradation data signal generator circuit(114). This circuit, along with converting a video signal which is an analog signal or a digital signal into a digital data signal for performing time partitioning gradation, is a circuit which generates timing pulses or the like which are necessary for performing time partitioning gradation display. |
