Abstract

The present invention relates to a liquid crystal display (LCD) and a manufacturing method thereof; the LCD comprises a backlight module and a display panel; an included angle ⊖ pb is between a normal direction of a light emission surface of the backlight module and a normal direction of a light emission surface of the display panel. By changing the relative positions of the display panel and the backlight module, the LCD and the manufacturing method thereof of the present invention decrease the phenomenon of asymmetrical light field in the LCD.

Claims (8)

1. A liquid crystal display (LCD), comprising a backlight module and a display panel, the backlight module comprising an optical film, wherein there is an included angle θ pb , which is larger than zero degrees, between a direction substantially perpendicular to a longest surface of the optical film and a normal direction of a light emission surface of the display panel; wherein the included angle θ pb is less than or equal to a light emission angle θ max ; wherein the light emission angle θ max is an included angle between a corresponding light emission direction of a maximum luminosity on a light emission surface of the optical film of the backlight module and the direction substantially perpendicular to a longest surface of the optical film of the backlight module; wherein an included angle θ mp between the corresponding light emission direction of the maximum luminosity and the normal direction of the light emission surface of the display panel is θ max −θ pb .

2. The LCD according to claim 1 , wherein the optical film comprises a diffuser film, a dual brightness enhancement film, a prism film, a microlens film and/or a lenticule film.

3. A liquid crystal display (LCD), comprising a backlight module and a display panel, the backlight module comprising an optical film, wherein there is an included angle θ pb , which is larger than zero degrees, between a direction substantially perpendicular to a longest surface of the optical film of the backlight module and a normal direction of a light emission surface of the display panel; wherein the included angle θ pb is less than or equal to a light emission angle θ max ; wherein the light emission angle θ max is an included angle between a corresponding light emission direction of a maximum luminosity on a light emission surface of the optical film of the backlight module and the direction substantially perpendicular to a longest surface of the optical film of the backlight module.

4. The LCD according to claim 3 , wherein an included angle ⊖ mp between the corresponding light emission direction of the maximum luminosity of the light emission surface of the backlight module and the normal direction of the light emission surface of the display panel is ⊖ max -⊖ pb .

5. The LCD according to claim 3 , wherein the optical film comprises a diffuser film, a dual brightness enhancement film, a prism film, a microlens film and/or a lenticule film.

6. A method for manufacturing a LCD, wherein the LCD comprises a backlight module and a display panel, the backlight module comprising an optical film; the method for manufacturing the LCD comprises a step of: (A) setting an included angle θ pb , which is larger than zero degrees, between a direction substantially perpendicular to a longest surface of the optical film of the backlight module and a normal direction of a light emission surface of the display panel; wherein the included angle θ pb is less than or equal to a light emission angle θ max , wherein the light emission angle θ max is an included angle between a corresponding light emission direction of a maximum luminosity on a light emission surface of the optical film of the backlight module and the direction substantially perpendicular to a longest surface of the optical film of the backlight module.

7. The method for manufacturing a LCD according to claim 6 , wherein an included angle ⊖ mp between the corresponding light emission direction of the maximum luminosity of the light emission surface of the backlight module and the normal direction of the light emission surface of the display panel is ⊖ max −⊖ pb .

8. The method for manufacturing a LCD according to claim claim 6 , wherein the optical film comprise a diffuser film, a dual brightness enhancement film, a prism film, a microlens film and/or a lenticule film.
