ABSTRACT:
An active matrix display apparatus includes an active matrix display panel comprising a plurality of pixels arranged in a matrix in a row direction and a column direction, each pixel being constituted by a plurality of subpixels; and a drive circuit for applying a voltage to each of the subpixels so that a polarity of the voltage is inverted at a predetermined period in each of a row direction and a column direction. The plurality of subpixels are arranged in the row direction at a period different from half of the predetermined period of polarity inversion of the voltage in the row direction, thus providing flicker-less color display device even when general driver ICs for dot inversion drive are used.
