摘要： The present disclosure proposes an array substrate and a display device. The array substrate includes gate lines, data lines, and pixel units. Each pixel unit includes a main-pixel zone, a first sub-pixel zone, and a second sub-pixel zone. The voltage levels of the main-pixel zone, the first sub-pixel zone, and the sub-pixel zone are completely different owing to the effect of capacitive coupling. In this way, the present disclosure can solve the problems of image distortion in the conventional VA liquid crystal panel.
