Abstract

The present invention relates to the field of display technology, and discloses a display device, which includes a backlight module and a display panel. A light alignment film is provided on the light exit side of the backlight module, and a lower polarizer is provided on the light incident side of the display panel. An upper polarizer is provided on the light exit side, and a switchable diffuser that can switch between a transparent state and a diffuse state is provided between the light alignment film and the lower polarizer; wherein, the light alignment film includes an alignment layer, The alignment layer has a plurality of first light-blocking walls arranged in parallel, there is a light-transmitting area between any two adjacent first light-blocking walls, and each of the first light-blocking walls faces its corresponding light-transmitting area The sides are light-blocking surfaces. The above-mentioned display device can be switched between a narrow viewing angle display and a wide viewing angle display according to the actual needs of the user, and can meet the user's demand for diversified display on the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] In the field of display technology, people have different requirements for the viewing angle width of liquid crystal display devices in different occasions. For example, people can use liquid crystal display devices with narrow The liquid crystal display device with different viewing angles can meet the requirement that multiple people watch the information displayed on the liquid crystal display device at the same time from multiple angles. [0003] However, in the prior art, it is impossible to switch between a wide viewing angle and a narrow viewing angle in the same liquid crystal display device, which cannot satisfy users' needs for diversified display of the liquid crystal display device. Contents of the invention [0004] The present invention provides a display device, which can switch between a narrow viewing an...
