摘要： Between a positive power supply 18 and a negative power supply 19, a p-channel transistor 11 and an n-channel transistor 14 are connected in series while a p-channel transistor 12 and an n-channel transistor 15 are also connected in series. An inverted input signal *Sig1 is input to the respective gates of the transistors 11 and 14, while an input signal Sig1 is input to the respective gates of the transistors 12 and 15. As a result, of a pair of the transistors connected in series, namely either the transistors 11 and 14 or the transistors 12 and 15, when one transistor turns ON, the other transistor turns OFF. Thus, generation of through currents is prevented.

摘要： A wide line portion is drawn from a cathode while another wide line portion is formed by gathered lines extending from cathode terminals. A contact of realtively large size is formed in a region where the two wide line portions overlap each other with an insulating film being interposed therebetween, so as to connect both wide line portions. Further, in this contact, the cathode terminals and the cathode are connected through an intermediate layer composed of a conductive oxide material. Thus, a reduction in the voltage to be applied to the cathode as a result of increased line resistance between the terminals and the cathode can be prevented, thereby preventing deterioration of display quality.

摘要： There are provided a data register (8) for driving an EL element (6) by a current flowing in a data line (3) via a TFT (5) while sequentially capturing input digital video data for each data line, a latch circuit (10) for holding the data received in the data register (8) during 1 H period, and n analog switches (120 to 123) provided between each data line (3) and a power supply line (11), to which n bit of digital video data for each one data line is input bit by bit as each control signal. The transistors constituting each switch are made different sizes. As the current amount flowing in each switch therefore differs, the EL element emits light with a luminance in accordance with the digital video data.

摘要： An insulator substrate (110) is provided with a display pixel region (200) comprising an electroluminescence element (160) having a cathode (167), emissive layer (166), and anode (161), and with first and second TFTs for driving the element. Surrounding the display pixel region (200), a peripheral drive circuit region (251) having a third TFT for driving each pixel is further provided on the insulator substrate (110). The cathode (167) is disposed in a region other than the peripheral drive circuit region (251). With this arrangement, generation of a back channel by applying the EL element potential to the cathode is prevented in a complementary TFT employed in the peripheral drive circuit region for controlling the display region, thereby suppressing changes in threshold values due to such back channel generation. As a result, an EL display device with reduced generation of penetration current and minimized increased current consumption is achieved.
