Because light deflects component 2 when pasting with substrate base plate 3, can appear counterpointing inaccurate problem, counterpoint inaccurate and lead to the light path inaccurate, in order to adjust the light and deflect 2 refraction light beams of component in the light transmission area A scope, make things convenient for the high accuracy laminating of light deflection component 2 and substrate base plate 3 simultaneously, add appointed refracting index between light deflection component 2 and substrate base plate 3, the even transparent gasket layer 8 of appointed thickness, transparent gasket layer 8 and substrate base plate 3 are peripheral to be pasted through pressure sensitive adhesive layer. The corresponding pixel pitch span may be from 1 micron to 5 millimeters.
In specific implementation, the surface of the transparent gasket layer, which is attached to the light deflection element, may be provided with or without a pressure-sensitive adhesive layer, and is designed according to actual attachment requirements.
Further, in a specific implementation, as shown in fig. 1 to 12, the display panel provided in the embodiment of the present invention further includes a polarizer 9 located at an outermost side of the display panel, where the polarizer 9 has the same function as the polarizer in the prior art, and is not described herein again.

In a specific implementation, in the display panel provided in the embodiment of the present invention, the triangular prism structure opposite to the weak refraction area of the light deflection element can tilt the collimated incident light therein to change the collimated incident light into non-collimated light, and the non-collimated light is deflected by the cylindrical curved lens structure or the cylindrical trapezoidal prism structure, so that at least a part of light incident from the substrate to the light shielding area is deflected to the light transmitting area, thereby improving the utilization rate of the light, and further improving the transmittance of the display panel. The light-reflecting weak area refers to a part of the light-deflecting element, which is opposite to the shading area and is parallel or very close to being parallel to the substrate, and is characterized by weak light-reflecting capacity. If the triangular prism structure is not provided, collimated light passing through the weak refraction area is not easily refracted to the light transmission area; the collimated light is absorbed by the light-shielding region or reflected by the metal of the light-shielding region and gradually attenuated.
In specific implementation, in the display panel provided by the embodiment of the present invention, the refractive index of the triangular prism structure, the cylindrical curved lens structure, the cylindrical trapezoidal prism structure and the resin layer is between 1.3 and 1.8, and is determined according to actual needs.
Further, in a specific implementation, in the display panel provided in the embodiment of the present invention, the structure of the light deflecting element may include only a cylindrical curved lens structure or only a cylindrical trapezoidal prism structure, or the structure of the light deflecting element is a combination of the cylindrical curved lens structure and a triangular prism structure, or the structure of the light deflecting element is a combination of the cylindrical trapezoidal prism structure and the triangular prism structure; the specific implementation process of the cylindrical curved surface lens structure, the cylindrical trapezoidal prism structure and the triangular prism structure can be as follows: the cylindrical curved lens structure can be formed by adopting a mold imprinting process or an ink-jet type 3D printing process, the cylindrical trapezoidal prism structure can be formed by adopting a mold imprinting process or an ink-jet type 3D printing process, and the triangular prism structure can be formed by adopting a mold imprinting process, an ink-jet type 3D printing process or a photoresist process. Specifically, when the light deflection element is arranged on the side of the substrate opposite to the opposite substrate, the light deflection element can be manufactured by adopting a bonding or in-situ ink-jet type 3D printing or photoresist process, and when the light deflection element is arranged on the side of the substrate facing the opposite substrate, the light deflection element can be manufactured by adopting an ink-jet type 3D printing or photoresist process, so that light in the shading area is deflected to enter the light-transmitting area.

In order to control the contrast, the cylindrical curved lens structure is preferably adopted in the embodiment of the invention, and the long axis of the cylindrical curved lens structure is parallel to the light absorption axis of the polarizer on the outer side of the array substrate.
Specifically, the display panel provided in the embodiment of the present invention is a Liquid Crystal Display (LCD) panel. In the specific implementation, other essential components of the liquid crystal display panel are all understood by those skilled in the art, and are not described herein nor should they be taken as limitations to the present invention.
It should be noted that, the display panel of the embodiment of the invention adopts the ADS/HADS design, and the black matrix in the direction of the gate metal layer is usually much wider than the corresponding shielding metal and is parallel to the light absorption axis of the polarizer of the array substrate. The polarizer of the TN design is designed to be inclined at 45 degrees. For the TN structure, a cylindrical curved surface lens structure is attached to the outer side of the polaroid, and the long axis of the cylindrical curved surface lens structure is parallel to the direction of the grid metal layer or the source drain metal layer of the pixel.
It should be noted that the triangular prism structure, the cylindrical curved surface lens structure and the cylindrical trapezoidal prism structure in the display panel of the embodiment of the invention all use single-layer lenses, so that the corresponding mold is simple, and the mold opening cost is low; combined with the common HADS lateral wide gate design, has less impact on color shift and viewing angle. Of course, in specific implementation, the triangular prism structure, the cylindrical curved lens structure and the cylindrical trapezoidal prism structure may also be distributed in a multi-layer structure, and designed according to actual needs.
Based on the same inventive concept, the embodiment of the invention further provides a display device, which comprises any one of the display panels provided by the embodiment of the invention. The display device may be: any product or component with a display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator and the like. Since the principle of the display device to solve the problem is similar to that of the display panel, the display device can be implemented by referring to the above embodiment of the display panel, and repeated descriptions are omitted.
In specific implementation, the display device provided by the embodiment of the invention further comprises a backlight source, and the backlight source is particularly suitable for the backlight sources with high local dimming series collimation, such as the double-LCD cell design, the Micro LED, the OLED and the like.
