ABSTRACT:
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.
