Abstract

The invention discloses a display panel and a display device, and relates to the field of display technology. The display panel includes a display area and a non-display area surrounding the display area, the non-display area includes a first frame area, and the first frame area includes a first sub-area and the second sub-area; the base substrate; the trace, the trace is located on the first side of the base substrate; in the direction perpendicular to the plane where the base substrate is located, the duty cycle of the trace in the first sub-area is smaller than that of the trace Duty cycle in the second sub-region; reflective layer, the reflective layer is located on the first side of the base substrate, and in the direction perpendicular to the plane of the base substrate, the reflective layer covers the first sub-region and the second sub-region respectively . The present invention effectively solves the problem that the difference between different areas in the non-display area of ​​the display panel visually has differences in brightness and darkness, which affects the display effect of the display panel.

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] The display panel generally includes a display area for image display and a non-display area for setting peripheral drive circuits. The non-display area also includes a plurality of traces. The external ambient light and some light inside the display panel will be reflected on the traces. Due to the difference in the number of traces, the line width of traces, and the distance between different areas in the non-display area, the duty cycle of traces in different areas in the non-display area is different, resulting in The reflection of light in different areas is different, which further leads to the difference in visual brightness of different areas in the non-display area, which affects the display effect of the display panel. SUMMARY OF THE INVENTION [0003] In view of this, the present i...
