Abstract

The invention discloses a display panel and a display device. The display panel includes: a substrate including a display area and a first non-display area, the display area surrounding the first non-display area; and a plurality of pixel circuits arranged in a plurality of rows in the display area, each row of pixel circuits including a plurality of pixel circuits arranged in a first direction, the plurality of rows of pixel circuits being arranged in a second direction, the second direction intersecting the first direction, each pixel circuit including a semiconductor layer for forming a transistor active layer, and the semiconductor layers of every two adjacent pixel circuits being arranged at intervals. According to the display panel provided by the embodiment of the invention, the lengths of the semiconductor layers connected with the pixel circuits tend to be consistent, so that the characteristic difference of regional transistors caused by different lengths of the connected semiconductor layers is reduced, the characteristics of the transistors with the same function of the pixel circuits in the display area tend to be consistent, the brightness uniformity of a display image of the display area is improved, and the possibility of uneven brightness display is reduced.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] With the continuous development of display technology, users have more and more functional requirements for electronic devices including display panels. For example, in electronic devices such as mobile phones and tablet computers, it is necessary to integrate front cameras, Infrared sensor and other functional modules. [0003] In the prior art, the display panel may include a part of the non-display area surrounded by the display area, and functional modules such as a front camera and an infrared sensor may be integrated in the non-display area, so that the functional modules and the display panel are compactly integrated on the electronic device . However, in the above-mentioned display panel, brightness display unevenness in different regions of the display panel is prone to occur. Contents of the invention ...
