Abstract

This invention provides a thin film transistor LCD and its process method. This thin film transistor LCD comprises a thin film transistor base plate on the color filter layer, wherein, the thin film transistor is located on the color filter layer and the data line is located between the color filter layer and down base plate and the thin film transistor is coupled between the data line and the picture element electrode.

Description

technical field [0001] The invention relates to a color liquid crystal display and a manufacturing method thereof. In particular, it relates to a color liquid crystal display including an integrated switch component (such as a thin film transistor), a color filter layer and a light-shielding structure on the same substrate. Background technique [0002] Generally, a thin film transistor (TFT) liquid crystal display (liquid crystal display, LCD) includes a lower substrate, a thin film transistor (as a switching element) formed on the lower substrate, an upper substrate opposite to the lower substrate, and a thin film transistor formed on the upper substrate. The red, green and blue color filter layer, and the liquid crystal layer sealed in the gap between the two substrates. [0003] figure 1 A cross-sectional view of a conventional thin film transistor liquid crystal display (TFT LCD) is shown. [0004] In the figure, an etch stopper inverse staggered type (etch stopper i...
