Problems solved by technology

However, the polarizer will reduce the transmittance of light, so it will reduce the overall optical efficiency of the LCD
In addition, the backlight module accounts for a considerable proportion of the thickness of the LCD, so it hinders the reduction of the thickness of the LCD

Abstract

An embodiment of the present invention provides a display device. The display device includes a first substrate, a second substrate, a light guide structure, a first light-emitting module, an element array and a liquid crystal switching layer. The first substrate has an inner surface facing the second substrate. The light guide structure is disposed on the inner surface of the first substrate. The first light emitting module is disposed on the inner surface of the first substrate and adjacent to one side of the light guide structure. The element array is disposed on the second substrate. The liquid crystal switching layer is disposed between the light guide structure and the second substrate.

Description

technical field [0001] The present invention relates to a display device, and in particular to a display device with a light source disposed on the side of an active array. Background technique [0002] The flat panel display has the advantages of small volume, light weight, etc., so it can be widely used in modern electronic products. Flat panel displays include various types, among which liquid crystal displays are the most common. Generally speaking, a liquid crystal display includes a backlight module, a pair of polarizers located on one side of the backlight module, and a liquid crystal module located between the pair of polarizers. The above pair of polarizers can be used to filter the polarization state of light. However, the polarizer reduces the transmittance of light, thus reducing the overall optical efficiency of the liquid crystal display. In addition, the backlight module accounts for a considerable proportion of the thickness of the liquid crystal display, ...
