Embodiment Construction

[0034] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0035] When the external natural light or the light emitted by the LED inside the display device enters from the edge of the polarizer, it can exit from the visible area of ​​the display device. At this time, the light emitted from the display device from the edge of the polarizer can enter the human eye, so that the user can see At the edge of the polarizer, edge leakage of the polarizer occurs, and the edge leakage of the polarizer usually manifests as bright lines, di...

Abstract

The invention discloses a display device. The display device includes: a display panel; an optical functional layer located on the light-emitting side of the display panel; a light-shielding layer located on the side of the optical functional layer away from the display panel, and the light-shielding layer is located in the non-visible area and surrounds the visible area; wherein, The optical function layer includes a connected first part and a second part, the first part is located in the non-visible area, the first part includes a first surface close to the display panel, the second part includes a second surface close to the display panel, and the first surface There is a height difference between the second surface and the second surface in the thickness direction of the display device, and the first surface is closer to the light-shielding layer than the second surface. The embodiments of the present invention improve or solve the problem of edge leakage of polarizers.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display device. Background technique [0002] With the development of the display industry, the full-screen display technology has become the mainstream of the display device. It is the key to realize the full-screen display to increase the screen-to-body ratio of the full-screen by reducing the frame of the non-display area. [0003] The narrow bezel design of the current display device is prone to edge leakage of the polarizer, resulting in bright lines, different colors, and even mura on the four sides of the visible area of ​​the display device, which greatly reduces the display quality of the display device, thereby affecting consumers' overall understanding of the display device. Screen product experience. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a display device to improve the ...
