Abstract
A color filter is disposed on a switching element array substrate. The color filter is composed of a plurality of kinds of color elements and an aperture. Two of the filter elements are overlapped at one end portion thereof. Each of the filter elements is covered with a pixel electrode. The pixel electrode is connected to the switching element through the aperture. This structure reduces electric coupling between the pixel electrode and the gate and signal lines. Optimum conditions among the overlapped width, and the aperture diameter and location are set to prevent the filter element from peeling off the array substrate so that the production yield can be significantly improved.
