Display panel and display device

Abstract

The invention discloses a display panel and a display device. The display panel comprises a first substrate, a second substrate and a display dielectric layer, wherein the second substrate is arranged opposite to the first substrate, the display dielectric layer is arranged between the first substrate and the second substrate, the second substrate comprises a black matrix, the black matrix comprises multiple first strip-shaped units which extend in the first direction and multiple second strip-shaped units which extend in the second direction, the first strip-shaped units and the second strip-shaped units are crossed to define subpixels of the display panel, the first direction is perpendicular to the second direction, and both the first direction and the second direction are parallel to the plane in which the first substrate is located; the first substrate comprises multiple shielding walls which are arranged on the side, close to the second substrate, of the first substrate, and the orthographic projection of the shielding walls on the second substrate is located in the area in which the black matrix is located. According to the display panel and the display device, the problems are solved that great viewing angles of the display panel leak light and color crossing occurs in the display panel are solved.

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] In the prior art, in order to prevent pixel light leakage and ensure the contrast of the display area, a black matrix (Black Matrix, BM) is provided in the display panel. The black matrix forms a dark area in the display panel, and the opening area surrounded by the dark area forms a display panel. In order to ensure that the aperture ratio of the display panel is not lost, the data lines and gate lines for controlling the pixels are arranged in the black matrix area.

[0003] figure 1 It is a schematic cross-sectional view of a display panel in the prior art. When the pixel P1 is on and the pixel P2 is dark, looking at the position S1, it can be seen that the light G1 emitted by the area of ​​the pixel P1 is transmitted from the display panel, and the display panel has a large viewing angle. ...
