Problems solved by technology

However, the transmittance and aperture ratio of existing high-PPI liquid crystal display devices are still low
In order to improve the transmittance and aperture ratio of liquid crystal display devices, the general method is to use new materials or new technologies such as low-temperature polysilicon technology (LTPS, LowTemperaturePoly-silicon), organic light-emitting diode technology (OLED, OrganicLightEmittingDiode), etc., but new materials And the process conditions of new technologies are harsh and the yield rate is low

Abstract

The invention discloses a thin film transistor array substrate, and a manufacturing method and a liquid crystal display apparatus thereof. A pixel electrode is formed by two different transparent conductive layers, and the drain electrode pattern of the thin film transistor is connected with a first transparent conductive layer, so the drain electrode pattern can be connected with the pixel electrode without a through hole, and the connectivity is good, thereby the drain electrode pattern is reduced, the light transmission area is increased, and the penetration rate of the liquid crystal display apparatus adopting the thin film transistor array substrate is increased. The manufacturing method in the embodiment of the invention increases the penetration rate without reducing the thickness of the insulation protection layer in the area of the pixel electrode, makes the whole thin film transistor array substrate still have good evenness, and avoids appearance of interference electric fields, so the pixel has good color uniformity.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a thin film transistor array substrate, a manufacturing method thereof and a liquid crystal display device. Background technique [0002] At present, the display screens of liquid crystal display devices (LCD, Liquid Crystal Display) are getting larger and larger. In large-size display screens, the higher the number of pixels per inch (PPI, PixelsPerInch) is, the higher the display screen can be. The density of the display image, the richer the details of the image will be. However, the transmittance and aperture ratio of existing high-PPI liquid crystal display devices are still low. In order to improve the transmittance and aperture ratio of liquid crystal display devices, the general method is to use new materials or new technologies such as low-temperature polysilicon technology (LTPS, LowTemperaturePoly-silicon), organic light-emitting diode technology (OLED, OrganicLigh...
