Abstract

The embodiment of the invention provides a display panel and a display device. The display panel includes a first display substrate and a second display substrate disposed opposite to each other and afunctional layer; the functional layer is located on a display surface of the display panel, and includes at least three layers of film layers, and the adjacent two film layers have different refractive indices for selective transmitting of lights of different wavelengths. The display panel can greatly reduce the radiant energy of a blue light, avoid the damage caused by the blue light transmitting to eyes, and can also cut off the lights of the specified wavelength, the color gamut of the display panel is improved, the optical performance of the display panel is improved, and the use experience of a user is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a display panel and a display device. Background technique [0002] With the continuous development of smart terminal devices, people spend more and more time using smart terminal devices, and the damage to the eyes caused by the screen is also increasing. Especially, in the field of virtual reality and augmented reality display technology, users need to view Watching the screen, the blue light radiation generated by the screen will further increase the damage to the eyes, and the screen color gamut of existing smart terminal devices is generally low, which affects the user experience. Contents of the invention [0003] In view of the shortcomings of the existing methods, the present application proposes a display panel and a display device to solve the problems in the prior art that the blue light radiation generated by the scree...
