摘要： A display device includes a plurality of light emitting elements arranged in a matrix. A scan signal is made to flow into a gate signal line and a data signal is made to flow into a source signal line so that the data signal is applied to a source electrode and the scan signal is supplied to a gate electrode of a control TFT arranged at a portion where the both signal lines intersect when viewed from above. Thus, when the control TFT is turned ON, a drive TFT having a gate electrode connected to the drain electrode is turned ON, so that current is supplied from a power supply line via the source electrode and the drain electrode of the drive TFT to an organic EL element and the organic EL element emits light. A holding capacity is present between the control TFT and the drive TFT. Even when the scan signal becomes LOW level and the control TFT turns OFF, the gate potential of the drive TFT is held for a predetermined period of time by the holding capacity and the organic EL element continues to emit light.

摘要： An EL element (60) comprises an anode (61), a cathode (67), and an emissive element layer (66) interposed between the two electrodes. A TFT is connected to the anode (61) at its source electrode (33s). The peripheral portion of the anode (61) and the entire region over the TFT are covered with a planarizing insulating film (17), and a part of the exposed portion of the anode (61) is connected to the emissive element layer (66). According to the above arrangement, it is possible to prevent disconnection of the emissive element layer (66) which may be caused by an uneven surface created by the thickness of the anode (61), and to avoid formation of a short circuit between the anode (61) and the cathode (67).

摘要： Plurality of pixels (102) are arranged on the substrate. Each of the pixels (102) is provided with an EL element which utilizes as a cathode a pixel electrode (105) connected to a current control TFT (104). On a counter substrate (110), a light shielding film (112) is disposed at the position corresponding to periphery of each pixel (102), while a color filter (113) is disposed at the position corresponding to each of the pixels (102). This light shielding film makes the contour of the pixels clear, resulting in an image display with high definition. In addition, it is possible to fabricate the EL display device of the present invention with most of an existing manufacturing line for liquid crystal display devices. Thus, an amount of equipment investment can be significantly reduced, thereby resulting in a reduction in the total manufacturing cost.

摘要： An EL display device capable of producing a vivid multi-gradation color display, and an electronic device having the EL display device. An electric current supplied to an EL element 110 is controlled by providing a resistor 109 between a current control TFT 108 and the EL element 110 formed in a pixel 104, the resistor 109 having a resistance higher than the on-resistance of the current control TFT 108. The gradation display is executed by a time-division drive system which controls the emission and non-emission of light of the EL element 110 by time, preventing the effect caused by a dispersion in the characteristics of the current control TFT 108.
