Embodiment Construction

[0039] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.

[0040] Hereinafter, a three-dimensional display device according to a first embodiment will be described in detail with reference to the accompanying drawings.

[0041] Such as figure 1 As shown, the three-dimensional display device according to the first embodiment includes a display panel 1 on which an image is displayed, a backlight 2 generating light to be supplied to the display panel 1, and a spacer 3, wherein the spacer 3 is provided on the display panel 1. The distance between the display panel 1 and the light guide module 22 is kept constant with the light guide module 22 which will be described below.

[0042] The display panel 1 is formed by a liquid crystal panel having a substantially square plate shape.

[0043] The backlight 2 includes: a pair of three-d...

Abstract

Disclosed herein is a three-dimensional display apparatus having a light guide module which guides light emitted from a backlight to a display panel. The three-dimensional display apparatus includes a first light guide, a second light guide, and an emission pattern which emits light toward the display panel, and viewing distances between both eyes of a user and the display panel are determined by a thickness of the second light guide regardless of a thickness of the first light guide, thus the desired thickness of the light guide module is able to be freely designed by a designer.

Description

technical field [0001] Embodiments of the present invention relate to a three-dimensional display device capable of displaying stereoscopic images. Background technique [0002] In general, since a display device is a device capable of displaying images, a monitor or a television is included therein. [0003] Recently, three-dimensional display devices among such display devices have been proposed to display three-dimensional images in addition to two-dimensional images. [0004] A three-dimensional display device includes a display panel having a liquid crystal panel and a backlight disposed at the back of the display panel and configured to generate light to be supplied to the display panel. [0005] The backlight includes a pair of three-dimensional light sources disposed on both rear sides of the display panel, a light guide disposed between the two three-dimensional light sources and configured to guide light emitted from the three-dimensional light sources to the disp...
