Finally, the light reaches the transparent ITO conductive film 26, and the transparent ITO conductive film 26 is used to provide electrical signal transmission and display effects in the liquid crystal screen, effectively improving the optical performance of the display screen.

[0041] Reference Figure 1-Figure 3 In one embodiment, a specified interval is formed between the transparent ITO conductive film 26 and the reflective layer 4 by setting a transparent column, and the liquid crystal layer 3 is filled in the specified interval.

[0042] In the above embodiment, a plurality of transparent columns are arranged between the transparent ITO conductive film 26 and the reflective layer 4.

[0044] In the above embodiment, the polarizing composite layer 1 includes a single-layer polarizer 10 and a diffusion layer 12. The single-layer polarizer 10 is arranged on one side of the diffusion layer 12 so that it is in the outermost layer for receiving external light. The diffusion layer 12 is located between the single-layer polarizer 10 and the one-way transparent black matrix layer 20, wherein the single-layer polarizer 10 only allows light with a specific polarization direction to pass through, and filters out polarized light in other directions, thereby controlling the light transmittance of the display. The light passing through the single-layer polarizer 10 enters the diffusion layer 12, effectively homogenizing the light passing through, reducing hot spots or light spots caused by direct light, and the light passing through the diffusion layer 12 then reaches the one-way transparent black matrix layer 20, which can absorb part of the light while allowing another part of the light to pass through, thereby improving the contrast of the displayed image.

[0045] Reference Figure 1 In one embodiment, the polarized composite layer 1 further includes a phase adjustment layer 11 , and the phase adjustment layer 11 is disposed between the single-layer polarizer 10 and the diffusion layer 12 .

[0046] In the above embodiment, the polarized composite layer 1 also includes a phase adjustment layer 11, wherein the phase adjustment layer 11 is located between the single-layer polarizer 10 and the diffusion layer 12. The light passing through the single-layer polarizer 10 then enters the phase adjustment layer 11. The phase adjustment layer 11 can adjust the phase of the light passing through, affect the fluctuation state of the light, and improve the color and contrast of the displayed image. The light passing through the phase adjustment layer 11 continues to move forward and passes through the diffusion layer 12. The diffusion layer 12 further uniformizes the light, reduces light spots and hot spots, and ensures the consistency of the brightness of the displayed image. Therefore, by stacking the single-layer polarizer 10, the phase adjustment layer 11, and the diffusion layer 12 in sequence from the outside to the inside, the large-angle incident light can be adjusted to the vertical direction. If the light is incident at a large angle, reflection may occur between different layers, resulting in image distortion. By adjusting the light to the vertical direction, this distortion can be reduced, and the clarity of the displayed image, as well as the accuracy and saturation of the color, can be improved.

[0048] In the above embodiment, the thin film transistor composite layer 5 includes an insulating layer 50, a thin film transistor layer 51 and a thin film transistor glass layer 52, wherein the insulating layer 50 is arranged on the side of the reflective layer 4 away from the liquid crystal layer 3, so that the insulating layer 50 is located between the reflective layer 4 and the thin film transistor layer 51. Since the reflective layer 4 is made of metal, the insulating layer 50 is required between the reflective layer 4 and the electrode, which effectively isolates the electrical signal between the electrode and the reflective layer, avoids unnecessary electrical connection, and ensures the normal operation of the thin film transistor composite layer 5. The thin film transistor layer 51 is arranged on the thin film transistor glass layer 52, so that the thin film transistor layer 51 is located between the insulating layer and the thin film transistor glass layer 52. When the light reaches the reflective layer 4, the reflective layer 4 reflects back the light that is not absorbed by the one-way perspective black matrix layer 20 and the light that passes through the liquid crystal. The circuit of the thin film transistor layer 51 controls the electric field of the liquid crystal layer 3, and the liquid crystal molecules respond to the change of the electric field to adjust the amount of light passing through, forming the brightness and color changes of the image, ensuring that the display can accurately control the display state of each pixel, thereby achieving high-quality image display.
