Abstract

The present invention provides a display panel and a display device, which relate to the field of display technology and are used for improving the large-view angle deviation problem of the display panel. The display panel includes a color filter electrode and a black matrix arranged in the same layer without overlapping, and the color filter electrode is used for conducting electricity and transmitting light of a predetermined color. The pixel definition layer is located on one side of the color filter electrode. The pixel definition layer includes a plurality of open areas and non-open areas. The orthographic projection of the opening area on the plane of the display panel is located within the orthographic projection of the color filter electrode on the plane of the display panel. The orthographic projection of the non-aperture area on the plane where the display panel is located covers the orthographic projection of the black matrix on the plane where the display panel is located. The light emitting layer and the pixel definition layer are located on the same side of the color filter electrode, and the light emitting layer is located in the opening area. The first electrode is located on a side of the light emitting layer away from the color filter electrodes.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] Organic Light-Emitting Diode (hereinafter referred to as OLED) display panels are widely used in the field of display technology due to their many advantages such as thinness, active light emission, and high contrast. However, when the current OLED display panel is displayed, its display effect will change with the change of viewing angle, especially when observed under a large viewing angle, the display panel will have a more obvious color shift phenomenon, which will affect the display effect. 【Content of invention】 [0003] In view of this, the embodiments of the present invention provide a display panel and a display device, which are used to improve the large-view angle misalignment problem of the display panel. [0004] In one aspect, an embodiment of the present invention provides a display...
