The polarizer 11 has an upper surface S1 , the light shielding element 14 is disposed above the polarizer 11 , and the upper surface S1 of the polarizer 11 has at least one edge B shielded. The shading element 14 has a lower surface S2 opposite to the upper surface S1 of the polarizer 11, the lower surface S2 has an inner edge C, and the inner edge C and the edge B of the polarizer 11 have a connecting line BC, and the polarizer 11 The angle between the reflected ray P1 of the edge B and the refracted ray P2 refracted into the air along the connecting line BC is 30 degrees to 90 degrees with the horizontal direction. It should be noted that the horizontal direction is a direction parallel to the upper surface S1 of the polarizer 11 when the display device 100 is placed horizontally, such as the X-axis direction in FIG. 2 . In addition, only one edge B of the upper surface S1 of the polarizer 11 is marked in FIG. 2 . It can be understood that the upper surface S1 of the polarizer 11 may have multiple edges. The figure formed by connecting the four sides is a rectangle, and the shading element 14 can be arranged in a ring shape so that the four sides of the polarizer 11 can be effectively shielded, but the present invention is not limited thereto.

The upper surface is a side close to the user, and some functional coatings (not shown) may be formed on the upper surface, such as an anti-reflection layer, an anti-fingerprint layer, an anti-glare layer or combination of the foregoing. The lower surface of the cover plate 10 is opposite to the upper surface, and the end surface is adjacent to the upper surface and the lower surface. Further, the end surface of the cover plate 10 has a stepped portion 10a, and the stepped portion 10a may be formed by machining a groove on the end surface of the cover plate 10 so that the area of the upper surface of the cover plate 10 is smaller than the area of the lower surface. In other embodiments, the cover plate 10 can also be formed by stacking multiple substrates. For example, the cover plate 10 includes a first substrate (not shown in the figure) and a second substrate (not shown in the figure), and the area of the first substrate is smaller than that of the second substrate. Regarding the area of the substrates, the first substrate and the second substrate are overlapped and stacked at the center to form the stepped portion 10 a of the cover plate 10 . The cover plate 10 is made of a transparent insulating material, such as glass, acrylic (PMMA), polyvinyl chloride (PVC), polypropylene (PP), polyethylene terephthalate (PET), polynaphthalene Ethylene glycol diformate (PEN), polycarbonate (PC), polystyrene (PS) and other transparent materials, and can also be made of the above transparent materials and then strengthened.

The light-shielding element 14 is disposed on the stepped portion 10 a of the cover 10 , and the upper surface of the light-shielding element 14 is flush with the upper surface of the cover 10 , so that the side of the display device 100 close to the user is more flat. The material of the light-shielding element 14 includes opaque insulating material, such as plastic, insulating ink or photoresist. In this example, the shading element 14 is illustrated by taking a plastic shading plate (Bezel) as an example.

The light-shielding element 14 and the cover plate 10 can be connected by glue, or by in-mold injection molding. For example, the cover plate 10 is placed in a mold, and then molten plastic is injected to cover the surrounding end surfaces of the cover plate 10 to form The light shielding element 14 is integrated with the cover plate 10 .

The polarizer 11 is a part of the display module 20. Generally, the display module 20 also includes other optical elements, such as color filters, liquid crystal layers, upper and lower substrates of the liquid crystal layer, and backlight modules. Here, for the sake of brevity, the display module 20 Other optical elements are collectively referred to as an optical component 12 , and the optical component 12 is located below the polarizer 11 .

The material of the second adhesive layer 13 can be selected from transparent optical adhesive, liquid optical adhesive, pressure sensitive adhesive and the like. The refractive index of the second adhesive layer 13 is preferably the same as or close to the refractive index of the cover plate 10, so that when the reflected light of the polarizer 11 passes through the second adhesive layer 13 and enters the cover plate 10, it will not be larger. offset.

In the embodiment of the present invention, the range of the polarizer 11 is shielded by rationally setting the light-shielding element 14, that is, the reflected light of the edge B of the polarizer is refracted into the air along the connection line BC, and the angle between the refracted light and the horizontal direction is 30 degrees to 30 degrees. 90 degrees can make the edge of the polarizer 11 invisible when the horizontal viewing angle ranges from 30 degrees to 90 degrees. Specifically as shown in FIG. 2, the reflected light from the edge B of the polarizer 11 is light P1, and the light P1 is the line connecting the edge C of the lower surface S2 of the shading element 14 in FIG. 2 and the edge B of the upper surface S1 of the polarizer 11. The refracted ray P1 refracted into the air through the cover plate 10 is the ray P2, and the angle between the ray P2 and the normal line (for example, the Y axis) is defined as the angle a. At this time, the viewing angle is 90 degrees minus the angle a, that is The included angle between the ray P2 and the upper surface of the cover plate 10 . The angle between the ray P1 and the normal is defined as b, then b=arcsina/n, where n is the refractive index of the cover plate 10 relative to air. As long as it is ensured that the shading element 14 can block the light P1, the edge B can be made invisible when the viewing angle is (90°−a) to 90°. The distance D between the inner edge C of the lower surface S2 of the light shielding element 14 and the edge B of the polarizer 11 in the horizontal direction, that is, the overlapping distance of the projections of the light shielding element 14 and the polarizer 11 in the horizontal direction D=H*tanb= H*tan(arcsina/n), where H is the vertical distance from the lower surface S2 of the shading element 14 to the upper surface S1 of the polarizer 11. In this way, the value of D can be reasonably set according to the angle a and the distance H, so that the edge B of the polarizer 11 is invisible. It should be noted that when the viewing angle is smaller, that is, the angle a is larger, or H is larger, the value of D is also larger. Generally, when the user uses the display device normally, the horizontal viewing angle is generally not less than 30 degrees, because when the viewing angle is less than 30 degrees, on the one hand, the image displayed by the display device 100 may not be easily viewed by the user; on the other hand, if polarized light is to be avoided For the problem that the edge of the sheet 11 is visible, the distance D needs to be set very large, which may result in a large area of the non-visible area N of the display device 100 , which is not conducive to the design of the narrow frame of the display device 100 . The utility model comprehensively considers the above-mentioned factors, and by reasonably setting the shading element 14 to cover the range of the polarizer 11, when the horizontal viewing angle range is 30 degrees to 90 degrees, the shading element 14 can block the reflected light P1 at the edge of the polarizer 11, so that the polarized light The edges of the sheet 11 are invisible, thereby improving the visual effect of the display device 100 . For example, taking the cover plate 10 as an example, n is approximately 1.48 to 1.5, and when the distance H is in the range of 0.1 mm to 3.5 mm, the distance D is in the range of 0.06 to 1.9 mm. In this way, it can be ensured that the edge B of the polarizer 11 is not visible when the viewing angle is from 45 degrees to 90 degrees, and at the same time, the visible area M is not too small, so that the visible area M can be improved while improving the visual effect of the display device 100 .
