Problems solved by technology

[0006] However, the viewing angle control film according to the related art restricts the viewing angle equally to two directions on the horizontal axis (ie, left and right directions)
[0007] Therefore, the brightness of the images respectively output to the driver and the passenger located in the two directions of the horizontal axis is reduced, so the visibility of the image by both the driver and the passenger is reduced
In particular, the visibility of the driver who is located more laterally on the horizontal axis than the passenger is severely reduced, so the driver may not be able to view the image in the event that the driver needs to view it

Abstract

A viewing angle control film and a liquid crystal display device including the same are disclosed. The liquid crystal display device includes a liquid crystal panel, a backlight unit below the liquidcrystal panel, and a viewing angle control film between the liquid crystal panel and the backlight unit. The viewing angle control film includes a plurality of separation wall patterns that constituteeach of a plurality of separation wall group arranged along a first axis, and that each extend along a second axis perpendicular to the first axis. The plurality of separation wall patterns are reduced in height along a direction of the first axis.

Description

technical field [0001] The invention relates to a viewing angle control film and a liquid crystal display device comprising the viewing angle control film. Background technique [0002] Facing the information society, the demand for display devices is increasing. Recently, flat panel display devices such as liquid crystal display (LCD) devices, plasma display panel (PDP) devices, and organic light emitting diode (OLED) display devices are used. [0003] Among these display devices, LCD devices are widely used due to advantages of light weight, thin profile, low power consumption, and the like. [0004] Recently, LCD devices have been used as information display devices for vehicles. For example, the LCD device is used as an instrument panel in front of the driver, or mounted on a center fascia and used as a central information display (CID), or mounted on a dash board in front of a passenger And as an Ambient Information Display (AID). [0005] In order to prevent a phen...
