Problems solved by technology

However, in the FFS display mode, due to the sudden attenuation of the brightness of the pixel electrode when the positive and negative frames are switched, the brightness difference at different moments is large, so TFT-LCD is more prone to flickering in the FFS display mode

Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings of the present invention. It should be understood that the specific embodiments of the present invention are only illustrative, and not intended to limit the protection scope of the present invention.

[0041] According to the direction of the electric field driving the liquid crystal, the thin film transistor TFT-LCD can be divided into a vertical electric field type and a horizontal electric field type. The vertical electric field type TFT-LCD is formed on the pixel electrode on the array substrate and the common electrode is formed on the color filter substrate. In the horizontal electric field type TFT-LCD, pixel electrodes and common electrodes are simultaneously formed on the array substrate. The horizontal electric field type TFT-LCD includes an in-plane switching (IPS) mode and a fringe field switching...

Abstract

The present invention is a display device for a thin film transistor and a display device having the display device, and the embodiment relates to an improved pixel structure. The pixel structure includes a first insulating layer, a common electrode layer composed of common electrodes, a second insulating layer, and a pixel electrode layer composed of a plurality of pixel electrodes. In the pixel structure, at least one of the upper surface of the first insulating layer, the upper surface of the second insulating layer, the common electrode layer and the pixel electrode layer has a protrusion. Embodiments of the present invention also relate to an array substrate having the above-mentioned pixel structure, a display device having the array substrate, a display panel having the display device, and a method for manufacturing the array substrate of the display device. The present invention can make it easier for the liquid crystal molecules at the position of the pixel electrode and the position between the adjacent pixel electrodes to rotate from the vertical state to the inclined state, so that the directionality of the rotation of the liquid crystal molecules is more clear, so that the liquid crystal molecules at the two positions The change speed of the liquid crystal molecules tends to be the same when they switch between the bright state and the dark state, and flickering phenomenon is not easy to occur.

Description

technical field [0001] The present invention relates to the field of display, in particular to a display device for thin film transistors, a display device with the display device, and a method for manufacturing the display device. Background technique [0002] In the field of display technology, a thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD) is a main liquid crystal display device. [0003] According to the direction of the electric field driving the liquid crystal, TFT-LCD can be divided into vertical electric field type and horizontal electric field type, wherein the horizontal electric field type TFT-LCD forms pixel electrodes and common electrodes on the array substrate at the same time. The horizontal electric field type TFT-LCD includes an in-plane switching (In-Plane Switching, IPS) mode and a fringe field switching (Fringe Field Switching, FFS) mode. [0004] Compared with the IPS display mode, the FFS display m...
