Abstract

The invention discloses a display panel and a display device to solve the problem in the prior art that it is difficult to design the masks of all the layers in a special-shaped display area. The display panel includes a display area, a peripheral area, and at least one middle area between the display area and the peripheral area. The edge of each middle area away from the display area includes afirst fillet having a first curvature radius. The edge of each middle area near the display area includes a first arc having a second curvature radius and a second arc having a third curvature radius.The display area and the middle areas include light emitting units arranged in an array and a pixel definition layer. Each light emitting unit includes a first electrode, a light emitting layer and asecond electrode, and the light emitting layer is between the first electrode and the second electrode. In the display area, the pixel definition layer is used for limiting the light emitting units.In each middle area, the pixel definition layer covers the first electrodes of the light emitting units.

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] OLED (Organic Light-Emitting Diode, organic light-emitting diode) display device has the advantages of low driving voltage, high luminous brightness, high luminous efficiency, wide luminous viewing angle, fast response speed, ultra-thin, light weight and compatible with flexible substrates. occupies an important position in the field. [0003] With the development of display technology, people have more and more diverse demands on display devices, and the shape of display panels is no longer limited to regular shapes such as rectangles, and irregular-shaped display panels gradually appear in people's field of vision. The special-shaped display panel is usually designed in a shape other than a regular rectangle, such as a convex polygon, a concave polygon, a circle, a ring, and the like. In order to mat...
