DISPLAY APPARATUS

Abstract

Provided is a display apparatus capable of reducing the scale of a drive circuit and decreasing the frame. A display area in which pixels are provided in matrix, a scanning line drive circuit for driving scanning lines, and a signal line drive circuit for driving signal lines are provided on a support substrate. The pixel within the display area is constituted with a plurality of dots. Each dot corresponds to a color filter of a certain color. The dot is in a laterally long shape, i.e. in a shape extending in a direction along the scanning lines. In other words, each dot is in a shape extending in parallel with the longitudinal direction of the signal line drive circuit. The color filters are of lateral stripe type, for example.
