Display panel and display device

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a display area and a non-display area; a substrate which comprises at least one organic layer and at least one inorganic layer, wherein the organic layer and the inorganic layer are arranged in a stacked mode; a plurality of pixel circuits, wherein each pixel circuit comprises a driving transistor; a driving transistor which comprises a first active layer; a semiconductor layer which comprises a shielding structure and an etching blocking structure, wherein the shielding structure is located in the display area, the vertical projection of the shielding structure on the film layer where the first active layers are located is overlapped with the first active layers, the etching blocking structure is located in the non-display area, and the etching blocking structure comprises at least one opening; and a blocking unit located in the non-display area, wherein the blocking unit comprises at least one groove structure and the groove structure penetrates through the first inorganic layer from the opening in the direction perpendicular to the plane where the first organic layer is located and extends into the first organic layer. According to the embodiment of the invention, the process cost of the display panel can be reduced, and the display effect of the display panel is improved.

Description

Technical field [0001] Embodiments of the present invention relate to the field of display, and more particularly to a display panel and a display device. Background technique [0002] Organic Light Emitting Diode, OLED Monitor has the advantages of self-illuminating, low power, wide viewing angle, and fast response speed, and is more considered to have a wide range of application prospects in various fields. [0003] A display device including an OLED display is typically composed of an OLED display panel, a system motherboard, and a housing, and the system motherboard can provide a corresponding display signal to the OLED display panel to control the OLED display panel to display the corresponding screen. The OLED display panel is typically provided with an OLED device for displaying a light-emitting device and a driving transistor for driving the OLED device to produce a respective drive current to drive the OLED device. However, because the OLED display panel is applied to th...

Problems solved by technology

However, when an OLED display panel is applied to a display device, the driving transistor in the display panel is affected by an external electric field, and the generated driving current deviates from the theoretically generated driving current, which makes the luminous brightness and color of the OLED device deviate. Thus affecting the display effect of the display panel
