Abstract

The invention provides a display panel and a display device. In the display panel, a pixel electrode is arranged on a substrate and located in a pixel area; gaps are formed between the pixel electrode and signal lines on the two sides of the pixel electrode; a first shielding part is arranged at one end, close to the corresponding thin film transistor, of each gap, and the orthographic projection of the first shielding part on the substrate at least covers the orthographic projection of part of the gap on the substrate; and each first shielding part is insulated from the signal lines and the pixel electrode. The first shielding parts can fully shield light leakage at the positions, close to the thin film transistors, of the gaps without being affected by the size of the thin film transistors and the distance between the first shielding parts and the thin film transistors, and the contrast ratio of the display device is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] At present, the aperture ratio of the display product will directly affect the transmittance of the product, thus directly determining the competitiveness of the display product. In traditional display products, on the display panel, there is a non-driving area (non-pixel area) between adjacent pixels, and the liquid crystal arrangement is not controlled, and light leakage will occur. [0003] Therefore, in the prior art, it is usually necessary to arrange a black matrix (Black Batrix, BM) on the color filter substrate disposed opposite to the array substrate, so as to block light leakage in the non-driving region. However, due to the long distance between the black matrix color filter substrate and the array substrate, the alignment offset during the masking process is relatively large, so the black ...
