Problems solved by technology
In the current design of the display panel, due to the large difference in film thickness between the display area and the non-display area of the display panel, the cell thickness uniformity of the display panel is affected, and the water vapor in the external environment is also easy to pass through. When the non-display area invades the display area, the intruded water vapor will react with the materials in the display panel, causing defects such as broken bright spots in the display area, which will affect the display effect

Embodiments of the present invention provide a display panel and a display device, which relate to the field of display technology and are used to improve the uniformity of the cell thickness of the display panel and reduce the risk of intrusion of water and oxygen in the external environment into the display panel. The display panel includes a stacked light-shielding layer, a color-resist layer and a planarization layer, and a sealant located in the non-display area; the light-shielding layer includes a first light-shielding structure located in the display area and a second light-shielding structure located in the non-display area; the first The light-shielding structure includes a plurality of hollow parts, and the second light-shielding structure does not include the hollow parts; the color-resist layer includes a first color-resist structure located in the display area and a second color-resist structure located in the non-display area; the first color-resist structure fills the hollow parts ; The second color-resisting structure is located on the side of the frame glue close to the display area; the length of the orthographic projection of the second color-resisting structure along the extension direction of the nearest frame glue is greater than the first color-resisting structure closest to the second color-resisting structure The length of the orthographic projection of the structure along the extension direction of the nearest sealant.
Description
【Technical field】 [0001] The present invention relates to the field of display technology, and in particular, to a display panel and a display device. 【Background technique】 [0002] The display panel includes a display area where sub-pixels are arranged for display, and a non-display area where peripheral circuits and wirings are arranged around the display area. In the current design of the display panel, due to the large difference in the film thickness between the display area and the non-display area of the display panel, the cell thickness uniformity of the display panel is affected, and the water vapor in the external environment is also easy to pass through. When the non-display area intrudes into the display area, the invading water vapor will react with the materials in the display panel, causing defects such as broken bright spots in the display area, affecting the display effect. [Content of the invention] [0003] In view of this, embodiments of the present...
