TFT array substrate and display panel

Abstract

The invention discloses a TFT array substrate and a display panel. The TFT array substrate comprises a plurality of sub-pixel regions distributed in an array; any two adjacent sub-pixel regions in a target direction comprise a first sub-pixel region and a second sub-pixel region; a wiring region is arranged between the first sub-pixel region and the second sub-pixel region; a first gap region is formed between the first sub-pixel region and the wiring region, and a second gap region is formed between the second sub-pixel region and the wiring region; and the first sub-pixel region is providedwith a first color resistor, the second sub-pixel region is provided with a second color resistor, and the first color resistor and the second color resistor overlap in the first gap region, the wiring region and the second gap region. According to the array substrate, the dark state light leakage brightness of the first gap region and the second gap region can be reduced, and the display contrastof the display panel can be improved.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a TFT array substrate and a display panel. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. The liquid crystal panel is a core component of the liquid crystal display. [0003] The structure of the liquid crystal panel is mainly composed of a thin film transistor array (Thin Film Transistor Array, TFTArray) substrate, a color filter (Color Filter, CF) substrate, and a liquid crystal layer (Liquid Crystal Layer) arranged between the two substrates. The rotation of the liquid crystal molecules in the liquid crystal layer is controlled by applying a driving voltage on the two glass substrates, and the light from the backlight module is refracted to produce a picture.

Problems solved by technology

[0005] However, when the display panel is working normally, the liquid crystal corresponding to the sub-pixel electrode needs deflection control. Affected by the DBS electrode, the liquid crystal state corresponding to the gap area between the sub-pixel area and the wiring area (sub-pixel electrode and DBS electrode) Not ideal (low liquid crystal efficiency), and the gap area has neither physical shading nor electric field shading similar to DBS electrodes, making the gap area prone to light leakage in the dark state, and the width of the gap area directly affects the final sub-pixel area The brightness of the dark state affects the display contrast of the display panel
