Abstract

The invention discloses a display panel and a display device. The display panel comprises an array substrate, wherein the array substrate comprises multiple thin film transistors; the thin film transistors comprise active layers, source electrodes and drain electrodes; the source electrodes and the drain electrodes are located on the same film layers; the source electrodes and the drain electrodesare electrically connected with the active layers; the source electrodes are provided with first via holes; the drain electrodes are provided with second via holes; the array substrate comprises shading parts; the film layers where the shading parts are placed are located on the sides, which are far away from the display surface of the display panel, of the film layers where the source electrodesand the drain electrodes are placed; the shading parts comprise first shading parts and / or second shading parts; the boundary of a positive projection of each first via hole on the film layer where each shading part is placed is located in each first shading part, and / or the boundary of a positive projection of each second via hole on the film layer where each shading part is placed is located ineach second shading part. The display panel improves the dark state light-leaking phenomenon at the via holes and improves the contrast.

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] Existing display panel technologies include liquid crystal display panels. The liquid crystal display panel includes an array substrate, a color filter substrate, and a liquid crystal molecular layer arranged between the array substrate and the color filter substrate. By applying a voltage to the pixel electrode and the common electrode, an electric field is formed. Control the deflection of the liquid crystal molecules, and then realize the screen display of the display panel. [0003] A plurality of thin film transistors are included in the array substrate as switching devices of the pixel units. Both the source and the drain in the thin film transistor need to be connected to the active layer of the thin film transistor through via holes. However, due to the reflection, diffraction, and sca...
