Abstract
A thin film transistor includes: a substrate; a thin film transistor formed on the substrate; a first color filter and a second color filter formed on the thin film transistor and each having a through hole; a capping layer formed on the first color filter and the second color filter; and a pixel electrode formed on the capping layer and connected to the thin film transistor through the through hole, wherein the capping layer formed on the first color filter has a first opening exposing the through hole of the first color filter, the size of the first opening is larger than the size of the through hole, the capping layer formed on the second color filter has a second opening disposed inside the through hole of the second color filter, and the size of the second opening is smaller than the size of the through hole. Accordingly, the capping layer completely covers the green color filter which prevents damage to the green color filter in a dry etching process, and also prevents changes of a color coordinate.
