Abstract

The embodiment of the invention provides a display panel and a display device. The display panel comprises at least one light-transmitting layer, wherein the light-transmitting layer comprises a first sub-region and a second sub-region which are different in thickness, the first subarea comprises a first surface close to one side of a display surface of the display panel and a second surface far away from one side of the display surface of the display panel, and the second subarea comprises a third surface close to one side of the display surface of the display panel and a fourth surface far away from one side of the display surface of the display panel; the phase difference between the light reflected by the first surface and the light reflected by the second surface is delta 1 for the visible light with the wavelength of lambda 0 emitted to the display panel; the phase difference between the light reflected by the third surface and the light reflected by the fourth surface is delta 2, wherein 0.5 pi < = | delta 1- delta 2 | < = 1.5 pi. According to the invention, the hue fluctuation problem caused by film thickness fluctuation in the light-transmitting layer process can be improved, so that the hue difference between different samples is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] The display panel is a multi-layer stacked structure, and the film structure in the display panel has a certain reflective performance to the ambient light. Currently, the display panel is generally required to have a neutral hue in the reflection of the ambient light, and there should be no obvious fluctuations between different batches. Otherwise, the appearance and color of the final modules in different batches are inconsistent, the visual effect is poor, and they cannot even be used as mass-produced products. Contents of the invention [0003] Embodiments of the present invention provide a display panel and a display device to solve the problem of large hue differences between different samples caused by film thickness fluctuations in the process. [0004] In a first aspect, an embodiment of the ...
