Abstract

The invention discloses a display panel and a display device, which belong to the technical field of display. The display panel includes scanning lines, data lines, pixel electrodes and a black matrix. The black matrix includes an externally expanded black matrix. The first black matrix is ​​connected, the scan line and the data line intersect to define the sub-pixel, the pixel electrode is arranged in the sub-pixel, the pixel electrode includes a first part and a second part that are connected to each other, and the first part includes a plurality of parts extending along the third direction. The first strip electrodes, the plurality of first strip electrodes are not connected, the first strip electrodes include the first subtype strip electrodes and the second subtype strip electrodes, the first subtype strip electrodes and the second subtype strip electrodes One of the strip-like electrodes overlaps with the externally expanded black matrix, and the other does not overlap with the expanded black matrix. The invention reduces the storage capacitance between the pixel electrode and the common electrode, improves the charging capability of the pixel, and improves the display effect.

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] At present, display technology has penetrated into all aspects of people's daily life, and accordingly, more and more materials and technologies are used for display screens. As an important part of the display device, the display panel is used to realize the display function of the display device. Today, the mainstream display panels mainly include liquid crystal display panels and organic light-emitting display panels. With the rapid development of display panels, display panels are increasingly used in various technical fields. For example, the display panel can be used on the vehicle central control display device. [0003] The existing in-vehicle central control display device generally integrates functions such as navigation, video playback, and function control. At this time, the displ...
