Description

Display device Technical Field The present invention relates to a display technology, and more particularly, to a display device. Background With the advancement of digital technology and related hardware and software, immersive experience (IMMERSIVE EXPERIENCE) has successfully attracted the favor of many users. For example, a caravan creates an atmosphere of an in-car space by providing a mood light area around its display screen, thereby allowing a user to get a sense of immersion. However, the conventional liquid crystal display may have dark areas in the ambient light region. The reason is to find out that in order to avoid the problem that the polarizer contracts under the high temperature environment, the size of the polarizer needs to be larger than that of the screen display area, so that the polarizer extends to a situation lamp area with different display modes from the display area, and a dark area appears in the situation lamp area. On the other hand, in order to shield the light leakage caused by poor arrangement of the liquid crystal layer at the edge of the display area and arrangement of the circuit area and the frame glue area, a shading layer is arranged at the junction of the display area and the situation lamp area to form a black area, so that the picture continuity of the display area and the situation lamp area is poor. Disclosure of Invention The invention provides a display device, which has better picture continuity of various display areas. The display device of the invention is provided with a display area and a situation display area outside the display area. The display device comprises a first substrate, a second substrate, a first polaroid, a second polaroid, a frame glue layer, a liquid crystal layer and an optical brightness enhancement film. The first substrate is provided with a pixel structure layer, a circuit element layer and a signal wiring layer. The second substrate is overlapped with the first substrate and is provided with a first shading pattern, a second shading pattern and a third shading pattern. The first polaroid is arranged on one side of the first substrate, which is away from the second substrate. The second polaroid is arranged on one side of the second substrate, which is away from the first substrate. The frame glue layer is clamped between the first substrate and the second substrate and defines a containing space. The liquid crystal layer is arranged in the accommodating space. The optical brightness enhancement film is arranged on one side of the first polarizer, which is away from the first substrate. The context display area includes a first sub-area, a second sub-area, and a third sub-area. The first subarea, the second subarea and the third subarea are internally provided with a first polaroid or a second polaroid. The first subarea is also provided with a first shading pattern, a frame glue layer and a signal wiring layer. A second shading pattern, a liquid crystal layer and a circuit element layer are also arranged in the second subarea. And a third shading pattern, a liquid crystal layer and a pixel structure layer are also arranged in the third subarea. The display area is provided with a first polaroid, a second polaroid, a third shading pattern, a liquid crystal layer, a pixel structure layer and an optical brightness enhancement film. The respective penetrations of the first sub-region, the second sub-region, the third sub-region and the display region are equal to each other. Based on the above, in the display device according to an embodiment of the invention, the three sub-areas of the display area and the situation display area other than the display area are respectively provided with the same or different numbers of the same or different kinds of the structural film layers. The penetration rates of the three areas are approximately equal through the matching combination of the structural film layers in the three subareas of the display area and the situation display area. Therefore, the juncture of the display area and the situation display area does not need to be provided with a shading structure to shade light leakage caused by poor arrangement of the liquid crystal layer, the frame glue layer and the circuit structure, which is beneficial to remarkably improving the picture continuity of the display area and the situation display area.
