ABSTRACT:
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.
