Display panel and display device

Abstract

The invention, which relates to the technical field of display, discloses a display panel and a display device. The display panel comprises an array substrate and a color film substrate which are oppositely arranged. A plurality of support columns are arranged between the array substrate and the color film substrate. The array substrate includes a substrate body, a plurality of data lines, a plurality of repairing lines and a plurality of pixel units arranged in an array, wherein the plurality of data lines, the plurality of repairing lines and the plurality of pixel units are arranged on thesubstrate body. Each pixel unit includes at least two sub-pixels arranged in a first direction; and each sub-pixel includes a thin film transistor. The support columns and the thin film transistors are at least stacked partially in a direction perpendicular to the array substrate; and the film thickness of the repairing line is d1 and the total film thickness of the source electrode of the thin film transistor and the semiconductor part of the thin film transistor is d2, wherein the d1 is smaller than or equal to the d2, the d1 is larger than 0, and the d2 is larger than 0. Therefore, the difficulty of repairing the data lines in the display panel is effectively reduced; meanwhile, the supporting performance of the supporting column in the display panel is not affected.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] Liquid crystal displays are widely used in various consumer electronics products such as mobile phones, televisions, digital cameras, notebook computers, and desktop computers because of their advantages such as high image quality, power saving, thin body, and wide application range. in the mainstream. [0003] The existing array substrate structure generally includes: a plurality of vertical data lines parallel to each other and arranged in sequence, a plurality of horizontal scanning lines parallel to each other and arranged in sequence, and a plurality of data lines and scanning lines electrically connected to each other. Thin film transistors arranged in an array, and pixel electrodes electrically connected to the thin film transistors. [0004] The scan lines provide scan signals to the t...

AI Technical Summary

Problems solved by technology

During the production process of the array substrate, due to the complex production process and the influence of the production process or the factory environment, the data line may be disconnected, resulting in black lines in the display screen, which seriously affects the display quality of the screen. Broken data cable to be repaired

For the existing array substrate structure, when the data line is broken, it can only be repaired with long lines at the periphery. The repair process is complicated, the repair effect is poor, and the success rate is low.
