Display device, electro-optical element driving method and electronic equipment
Abstract:
The present invention permits a capacitance value of an electro-optical element such as organic EL element to be arbitrarily set without changing the light extraction efficiency of a pixel. That is, the present invention permits a capacitance value Coled of an organic EL element (21) to be arbitrarily set by adjusting the light emission area of the organic EL element (21) without changing the light extraction efficiency of a pixel (20) in an organic EL display device. The organic EL display device has the pixels (20) arranged in a matrix form. A light extraction opening (56) is formed on the surface of the pixel with a light-shielding film (black matrix) (57). The light extraction opening (56) has an opening area smaller than the light emission area of the organic EL element (21).
