Liquid crystal display device and manufacture method thereof

Abstract

The invention discloses a liquid crystal display device and a manufacture method thereof, which relate to the field of liquid crystal displays and solve the problem that the traditional liquid crystal display devices with touch functions influence the brightness, the contrast and the definition of display frames. In the embodiment of the invention, a signal wire and a light-induced thin film transistor are additionally installed in the liquid crystal display device, and the light-induced thin film transistor is provided with an auxiliary spacer which has the gap with the light-induced thin film transistor; the surface of the auxiliary spacer is provided with a reflection layer, wherein the the drain electrode of the light-induced thin film transistor needs to be input to the signal wire, whereas the grid electrode and the source electrode of the light-induced thin film transistor are respectively connected to a grid electrode scanning line. The liquid crystal display device and the manufacture method thereof are mainly used for the liquid crystal displays, in particular to the liquid crystal displays with the touch functions.

Description

Liquid crystal display device and manufacturing method thereof technical field The invention relates to the field of liquid crystal displays, in particular to a liquid crystal display device in a liquid crystal display with touch function, and a manufacturing method of the liquid crystal display device. Background technique A liquid crystal display includes pixel units arranged in a matrix, and a driving circuit for driving the pixel units, and uses an electric field to control light transmittance of liquid crystals to display images. As shown in FIG. 1 , the liquid crystal display device 100 includes a thin film transistor (TFT, ThinFilmTransistor) array substrate 110 and a color filter glass substrate 120 facing each other, and the two substrates are sealed to the box by a sealant 130 to form the liquid crystal display device 100, And the TFT array substrate 110 and the color filter glass substrate 120 are coated with an alignment layer 160; the liquid crystal display de...
