Abstract

The invention provides a display panel and a mobile terminal. The display panel comprises a supporting layer, a display layer located on the supporting layer, and an optical device located on the side, away from the display layer, of the supporting layer and located in the first area. The supporting layer comprises a first supporting part located in the first area. According to the invention, a film layer of which the phase difference in the thickness direction is greater than or equal to 8000 nanometers or less than 10 nanometers is used as a supporting layer; the optical property of the supporting layer is improved, so that the birefringence phenomenon is relieved, and the rainbow pattern phenomenon is relieved; therefore, the working reliability of the under-screen optical device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to the field of display panel manufacturing technology, and in particular to a display panel and a mobile terminal. Background technique [0002] In order to realize the lightness and aesthetics of the display screen, the display screen application that uses the optical device under the screen to realize the functions of the fingerprint under the screen and the camera under the screen is born. [0003] At present, polyethylene terephthalate is generally used to make the substrate to carry the display layer, and to avoid scratching the display layer during the assembly process. However, after investigation, it was found that polyethylene terephthalate exists due to optical The phenomenon of birefringence caused by anisotropy seriously affects the reliability of the optical devices under the screen, and reduces the accuracy of fingerprint recognition and camera under the scre...
