Abstract

The invention discloses a display panel and a display device, which relate to the technical field of display. The display panel comprises a hollow part, a first non-display area, a display area and asecond non-display area; the display panel further comprises oppositely arranged color film substrate and array substrate, and a liquid crystal, wherein the array substrate comprises a first substrate, and a driving circuit layer located at one side, close to the color film substrate, of the first substrate; the color film substrate comprises a second substrate, and a black matrix and a color resistance layer both located at one side, close to the array substrate, of the second substrate; orthographic projection of the driving circuit layer and the color resistance layer is not overlapped withthe hollow part, and the hollow part comprises at least one first support column located between the first substrate and the second substrate; the display panel further comprises an upper polarizer and a lower polarizer, wherein the upper polarizer comprises a first through hole which penetrates through the upper polarizer along a thickness direction of the upper polarizer and is corresponding tothe hollow part, and the lower polarizer comprises a second through hole which penetrates through the lower polarizer along the thickness direction of the lower polarizer and is corresponding to thehollow part. Thus, realizing a light-transmitting function at a corresponding position of the hollow part is facilitated.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background technique [0002] At present, display devices such as mobile phones and tablet computers often need to reserve space for electronic photosensitive devices such as commonly used front cameras, infrared sensing devices, and fingerprint recognition devices. For example, when the electronic photosensitive device is a front-facing camera, it is usually set at the top of the front of the display device; Form a non-display area, thereby reducing the screen-to-body ratio of the device. [0003] In the prior art, in order to increase the screen ratio, a high light transmittance area can be set up in the display area of ​​the display panel to accommodate the above-mentioned electronic photosensitive device, wherein the high light transmittance area is usually made in the display area of ​​the display panel. Hole design, ...
