Abstract

The invention discloses a thin film transistor liquid crystal display device which comprises a plurality of pixel areas, wherein each pixel area comprises a thin film transistor, a transparent electrode, a pixel electrode and a shading electrode; each pixel electrode passes through each thin film transistor, is coupled with scanning lines and data wires, is overlapped with each transparent electrode, is insulated to each transparent electrode, and is overlapped with the scanning line at a former row or the scanning line at a latter row; each shading electrode is insulated to each pixel electrode; the edges of each shading electrode and each pixel electrode are overlapped at least partially; each shading electrode is insulated to the data wire, and is overlapped with the data wire; and each transparent electrode and each shading electrode are electrically connected with the scanning line at the former row or the scanning line at the latter row. According to the invention, the thin film transistor liquid-crystal display device leaves out a storage electrode wire occupying routing space of the conventional liquid-crystal display device, reserves the shading electrode, so that the aperture opening ratio of the pixels is increased.

Description

technical field

[0001] The present invention relates to the technical field of liquid crystal display, and more specifically relates to a thin film transistor liquid crystal display device and a manufacturing method thereof. Background technique

[0002] The information society increasingly needs thin and portable display devices, and the most mature product at present is a liquid crystal display device (Liquid Crystal Display, LCD). The liquid crystal display device is a non-active light-emitting device. When the liquid crystal display device is working, the backlight located behind the liquid crystal panel emits light, and at the same time, a voltage is applied to the liquid crystal through the electrodes on the substrate, and then the arrangement of the liquid crystal molecules is changed according to the applied voltage. , to control the amount of light passing through the liquid crystal to achieve the effect of displaying images.
