Embodiment Construction

[0085] Hereinafter, embodiments of a display device according to the present invention will be described with reference to the drawings.

[0086] refer to Figure 1 ~ Figure 3 , the configuration and operation of the display device according to the embodiment of the present invention will be described. Although a liquid crystal display device is exemplified below using a liquid crystal display panel as a display panel, the display panel used in the display device of the present invention is not limited thereto. As the display panel, for example, a display panel for PDP, an organic EL display panel, an electrophoretic display panel, etc. can also be used.

[0087] figure 1 It is a schematic cross-sectional view of a liquid crystal display device 100a according to an embodiment of the present invention. figure 2 is a schematic cross-sectional view of an end portion of the liquid crystal display device 100a. image 3 It is a schematic perspective view of a liquid crystal dis...

Abstract

A direct-view-type display device (100a) is provided with: a display panel (10), which has a display region (31) and a frame region (30) formed outside the display region; and a light guide element (20), which has a light incoming surface (21), a light outgoing surface (22), and a plurality of light guide sections formed between the light incoming surface (21) and the light outgoing surface (22). The light guide sections include a transparent section, and at least a part of the side surface of the transparent section is provided with a metal section. The light incoming surface (21) of the light guide element (20) overlaps a part (32) of the peripheral display region adjacent to the frame region (30) of the display panel (10) along a first axis (J1), and the light incoming surface is arranged in parallel to the surface of the display panel (10). In the light outgoing surface (22) of the light guide element (20), the distance from the light incoming surface (21) increases along the first axis (J1) toward the frame region (30) from the part (32) of the peripheral display region. Thus, the direct-view-type display device wherein the frame region of the display panel or a joint line formed when tiling is performed is not easily seen is provided with the structure which is simpler and lighter in weight compared with conventional structures.

Description

technical field [0001] The present invention relates to a display device, in particular to a direct-view display device. Background technique [0002] In recent years, there has been a strong demand for upsizing of televisions and display devices for displaying information. As a representative of large-scale display devices, there are display devices and projection display devices in which self-luminous elements such as light-emitting diodes (LEDs) are arranged in a matrix, but these are insufficient in terms of image quality, so direct-view display devices capable of high-quality display are expected. Further enlargement of type liquid crystal display (LCD) and plasma display (PDP). [0003] Since direct-view liquid crystal display devices and plasma processing devices are basically formed on glass substrates, their screen size depends on the size of the substrate. Currently, the largest glass substrate (mother substrate) used in the manufacture of liquid crystal display ...
