- the light emitted from the backlight 17 enters the liquid crystal layer through the absorption type lower polarizer 16 and the array substrate 15.
- the liquid crystal layer 14 is modulated while being passed through the liquid crystal layer 14, and finally, the color filter layer 13, the counter substrate 12, and the absorption type upper polarizer 11 are emitted to the display side of the liquid crystal display device.
- a liquid crystal display device includes: a display unit, a backlight, and a reflective polarizer positioned between the display unit and the backlight.
- a liquid crystal display device includes: a display unit, a backlight, and a reflective color film layer between the display unit and the backlight.
- FIG. 1 is a schematic structural view of a conventional liquid crystal display device
- FIG. 2 is a schematic structural view of a liquid crystal display device according to an embodiment of the present invention.
- FIG. 3 is another schematic structural view of a liquid crystal display device according to an embodiment of the invention. detailed description
- a liquid crystal display device includes: a display unit 2, a backlight unit 29, and a reflective polarizer 28 between the display unit 2 and the backlight 29.
- the display unit 2 includes: an array substrate 25; an opposite substrate 22 disposed opposite to the array substrate 25; an absorption type upper polarizer 21 disposed above the opposite substrate 22; a pigment type color film layer 23 under the opposite substrate 22; a liquid crystal layer 24 filled between the pigment type color film layer 23 and the array substrate 25; and an absorption type lower polarizing light disposed under the array substrate 15 Sheet 26.
- the backlight 29 is disposed below the absorption-type lower polarizer 26 of the display unit 2, and the reflective polarizer 28 is disposed between the absorption-type lower polarizer 26 and the backlight 29.
- the light emitted from the backlight 29 is incident on the reflective polarizer 28, and a part of the incident light polarizer 28 is reflected to obtain the reflected light 30, and the other portion passes through the reflective polarizer 28.
- the reflected light 30 can be returned to the backlight 29 and recycled to increase the overall brightness of the LCD.
- the liquid crystal display device may further include a reflective color film layer 27 located on the display unit 2 (the absorption type lower polarizer 26 of the display unit 2) and reflection. Between the polarizers 28. Referring to Fig. 2, the light passing through the reflective polarizer 28 is further incident on the reflective color film layer 27, and a part of the incident light is reflected by the reflective color film layer 27 to obtain reflected color light, and the other portion passes through the reflective color film layer. 27 as the display light. For example, for blue pixels, the reflective color film layer 27 passes blue light and reflects such as red light and green light. Light of other colors. The light reflected by the reflective color film layer 27 is scattered to the backlight 29 or other units, and the scattered light is reused by pixels such as green pixels or red pixels, thereby increasing the total brightness of the LCD and increasing the viewing angle. .
- a reflective color film layer 27 located on the display unit 2 (the absorption type lower polarizer 26 of the display unit 2) and reflection. Between the polarizers 28. Referring to Fig. 2, the

- the reflective color film layer 27 is aligned with the pigment type color film layer 23 so that the reflective color film layer 27 coincides with the pixel pattern of the pigment type color film layer 23.
- the color light reflected by the reflective color film layer 27 may include red, green, blue, cyan, magenta or yellow, and the number of color lights may be two. Or three or more.
- the reflective polarizer 28 may be a polarizer having a cholesteric liquid crystal, a multilayer reflective polarizer or a wire grid polarizer.
- the array substrate 25 can be made of a thin glass substrate having a thickness less than a predetermined threshold.
- the pigment type color film layer 23 is bonded to the opposite substrate 22.
- the pigment type color film layer 23 can also be bonded to the array substrate 25.
- the pigment type color film layer 23 may be disposed on the upper surface of the array substrate 25, in which case the liquid crystal layer 14 is filled between the opposite substrate 22 and the pigment type color film layer 23.
- FIG. 3 is another schematic structural view of a liquid crystal display device according to an embodiment of the invention.
- the structure shown in Fig. 3 differs from the structure shown in Fig. 2 in that a reflective color film layer 27 is located between the reflective polarizer 28 and the backlight 29.
- the other components of the structure shown in Fig. 3 are the same as those of Fig. 2, and their detailed descriptions are omitted here.
- the light emitted from the backlight 29 is first incident on the reflective color film layer 27, and a part of the incident light is reflected by the reflective color film layer 27 to obtain reflected color light, and the other portion passes through the reflective type.
- the light passing through the reflective color film layer 27 is further incident on the reflective polarizer 28, and a part of the incident light is reflected by the reflective polarizer 28 to obtain reflected light 30, and the other portion is used as a display light by the reflective polarizer.
