Abstract

Embodiments of the present invention provide a display panel and a display device. The display panel includes: a display area and a non-display area, the display area is a rectangle with at least one rounded corner; power signal lines arranged along the row direction and extending along the column direction, the power signal lines are electrically connected to the pixel units on the corresponding columns , the power signal line includes the first part of the line in the display area and the second part of the line in the non-display area, the first part of the line is set on the same layer as the source and drain metal layer of the thin film transistor in the pixel unit; a plurality of anode blocks, anode The block is located on the side of the thin film transistor away from the substrate; at least one second part of the power signal line in the rounded area is set on the same layer as the anode block. Through the above design, the second part of the line corresponding to the rounded area can be The line width becomes larger, thereby reducing the load gap between the power signal line corresponding to the rounded area and the power signal line corresponding to the non-rounded area, thereby improving the display effect of the display panel.

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] With the development of science and technology, people have more and more diversified demands on the screen of the display device. Therefore, the display area of ​​the display panel is often designed in a shape other than a regular rectangle. For example, the display area is designed as a rounded rectangle. After adopting the above design, the circuits located in the non-display area (such as pixel drive unit, anti-static wiring, etc.) The space is occupied, for example, the circuit arranged along the edge of the rounded corner occupies the setting space of the power signal line corresponding to the rounded corner in the non-display area in the row direction, so that the power signal line corresponding to the rounded corner is in the non-display area In order to avoid the electrical connection between t...
