Embodiment Construction

[0033] The following will clearly and completely describe the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0034] In a display panel using a color filter (color filter, CF) and a black matrix (BlackMatrix, BM), the method of increasing the area of ​​the black matrix is ​​usually used to continuously reduce the reflection of the display panel to ambient light, but this method will cause The brightness of the display at a larger viewing angle is rapidly attenuated. Therefore, the position of the black matrix is ​​set such that the maximum angle of light emitted from the edge of the light emitt...

Abstract

The invention provides a display panel and a display device, the display panel comprises a light-emitting area, a light-shielding area and a transition area, the transition area is located between the light-emitting area and the light-shielding area, the transition area surrounds the light-emitting area, and the light-shielding area surrounds the transition area; the length of the light-emitting area in the first direction is a first length, the length of the light-emitting area in the second direction is a second length, the first length is larger than the second length, and the first direction is perpendicular to the second direction; in the second direction, the distance between the light-emitting area and the light-shielding area is a first distance D1, in the first direction, the distance between the light-emitting area and the light-shielding area is a second distance D2, in the third direction, the maximum distance among the distances between the light-emitting area and the light-shielding area is a third distance D3, and the third direction is the pointing direction between the first direction and the second direction; according to the invention, the problem of picture brightness fluctuation of the display panel at each azimuth angle is relieved or even eliminated.

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] With the continuous development of science and technology, display devices are widely used in people's daily life and work to display colorful images. Wherein, the display device mainly performs display through the display panel, so the display effect of the display panel directly affects the experience of the user. [0003] In an existing display panel, when a user observes the panel through a large viewing angle, there will be brightness fluctuations visible to the naked eye on the screen, thereby affecting user experience. Contents of the invention [0004] In view of this, the present application provides a display panel and a display device, so as to alleviate or even eliminate the problem of image brightness fluctuation of the display panel at various azimuth angles. [0005] To achiev...
