Problems solved by technology
[0020] In this multi-viewpoint display device, when light from the backlight is incident on the parallax barrier 20, as shown by the arrow of the solid line in the figure, the light is absorbed by the parallax barrier 20 or reflected from the parallax barrier 20, which causes a decrease in luminance.
For example, it is known that when the parallax barrier is formed of black resin, the brightness in the middle viewing direction decreases

Embodiment Construction
[0043] Reference will now be made in detail to preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.
[0044] Figure 4 is a diagram illustrating the structure of the multi-viewpoint display device according to the first embodiment of the present invention. In this figure, only a 3-viewpoint display device in which different images are displayed in three different viewing directions is described. However, the present invention is not limited to the specific structure of the 3-viewpoint display device. That is to say, those skilled in the art should understand that the present invention is applicable to multi-viewpoint display devices with various structures, such as 2-viewpoint display devices and 4-viewpoint display devices.
[0045] Such as Figure 4 As shown in , the multi-viewpoint display device 100 includes a liquid crystal display panel 101; a backlight 130 for providing light to the liquid crystal display panel at the ...

Abstract
The invention relates to a multi-viewing display device that includes a display panel for displaying images and a backlight unit for supplying light to the display panel; and further a viewing converting unit for controlling the light path from the backlight unit to the display panel. The viewing converting unit is disposed between the backlight unit and the display panel, and is provided with a substrate and at least one parallax barrier on the substrate. The parallax barrier comprises a reflecting layer and a light blocking layer on the reflecting layer. A retroreflecting layer can be used to instead of the light blocking layer. A manufacture method of the multi-viewing display device is also disclosed.
Description
[0001] This application claims the priority of Korean Patent Application No. 141965 / 2007 filed on December 5, 2007 and Korean Patent Application No. 125815 / 2007 filed on December 31, 2007, both of which are hereby incorporated by reference in their entirety combined in a manner to serve as a reference for various purposes. technical field [0002] The invention relates to a multi-viewpoint display device, in particular to a multi-viewpoint display device capable of improving brightness and reducing crosstalk and a manufacturing method thereof. Background technique [0003] Recently, various portable electronic devices, such as mobile phones, personal digital assistants (PDAs), and notebook computers, have been rapidly developed due to their small size, light weight, and power-saving operation. Therefore, flat panel display devices, such as liquid crystal displays (LCDs), plasma display panels (PDPs), field emission displays (FEDs) and vacuum fluorescent displays (VFDs), are ...
