Referring to fig. 1, the display panel 900 includes a backlight module 91, a color resist layer 92, a light-gathering layer 93 and a glass cover plate 94 stacked in sequence. The backlight emitted from the backlight module 91 sequentially passes through the color resist 92 and the light-condensing layer 93, and is finally imaged near the upper surface of the glass cover plate 94. From the light path perspective, in the display panel 900, light is emitted from the light source of the backlight module 10, and except the direction perpendicular to the panel, the light is emitted and also emitted in many other directions, and then passes through the color resist layer 92, and for each sub-pixel of red, green, and blue of a pixel, a beam of light is emitted and then passes through the light-gathering layer 93. Because the light that incides condensing layer 93 is comparatively dispersed, behind condensing layer 93, a pixel that theoretically originally has become a little plane, can take place to crosstalk with other pixels. From an imaging angle, for the micro lens of the light-condensing layer 93, a focal plane should be designed near the upper surface of the glass cover plate 94, the distance is a focal length, the distance from the color-resist layer 92 to the light-condensing layer 93 is an object distance thereof, for a general display panel 900, the distance from the color-resist layer 92 to the light-condensing layer 93 is smaller than the distance from the upper surface of the glass cover plate 94 to the light-condensing layer 93, that is, the object distance is smaller than 1-fold focal length, according to a lens imaging formula, a virtual image is formed on the upper surface of the glass cover plate 94, and an image viewed by human eyes is not on the upper surface of the glass cover plate 94. In order to ensure that a real image can be formed, the object distance needs to be increased, and the thickness of the light-condensing layer 93 needs to be increased, however, the process difficulty of the thicker light-condensing layer 93 is greater, and the design of the thickness of the light-condensing layer 93 has a limit. Therefore, it is necessary to solve the problem of the virtual image generated by the condensing layer 93.

Referring to fig. 2 to fig. 3, a display device 100 according to an embodiment of the present disclosure will be described. The display device 100 comprises a backlight module 10, a color resistance layer 5, a light condensing layer 12 and a light transmitting cover plate 1 which are sequentially stacked, the display device 100 further comprises a collimation layer 11, the collimation layer 11 is used for reducing the divergence angle of light, and the light condensing layer 12 is used for focusing the light on the upper surface of the light transmitting cover plate 1; the collimation layer 11 is arranged between the backlight module 10 and the color resistance layer 5, or the collimation layer 11 is arranged between the color resistance layer 5 and the light condensation layer 12.

The display device 100 further comprises a collimating layer 11, the collimating layer 11 is used for reducing the divergence angle of light, and the light-condensing layer 12 is used for focusing light on the upper surface of the light-transmitting cover plate 1. The collimating layer 11 can modulate the diffused light into substantially parallel light, and compared with the diffused light, the substantially parallel light passes through the light-condensing layer 12 and then is focused near the upper surface of the light-transmitting cover plate 1 with a higher probability, so that the display picture is near the upper surface of the light-transmitting cover plate 1, and when people watch the display picture, the people can watch the effect of similar paper printed products, feel more comfortable and natural, and can solve the problem that fatigue or dizziness are easily caused when people watch the liquid crystal display panel 900 for a long time. The light-condensing layer 12 is used for focusing light on the upper surface of the light-transmitting cover plate 1, and in practical application, because of process errors or other reasonable factors, the light is not necessarily strictly focused on the upper surface of the light-transmitting cover plate 1, and a focal point generated by the light-condensing layer 12 may be just on the upper surface of the light-transmitting cover plate 1, or may be slightly higher than the upper surface of the light-transmitting cover plate 1, or slightly lower than the upper surface of the light-transmitting cover plate 1. In some examples, the distance from the focal point generated by the light-condensing layer 12 to the upper surface of the light-transmissive cover plate 1 may be within 30% of the thickness of the light-transmissive cover plate 1.

According to the principle of lens imaging, the lens imaging formula is as follows: 1/f is 1/u + 1/v. Where f represents the focal length, u represents the object distance, and v represents the image distance.

The display device 100 provided by the present application is provided with the collimating layer 11, which modulates the backlight emitted from the backlight module 10 to form collimated light, which is parallel light or approximately parallel light for the light-condensing layer 12.
