Embodiment Construction

[0078] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the illustrated embodiment.

[0079] figure 1 It is a schematic cross-sectional view of a direct-view display device 100A according to an embodiment of the present invention.

[0080] Such as figure 1 As shown, the liquid crystal display device 100A includes: a single liquid crystal display panel 10; a translucent cover 20 disposed on the observer side of the liquid crystal display panel 10; and a box 30.

[0081] The liquid crystal display panel 10 includes a display area 10A and a frame area 10F provided outside the display area 10A. The liquid crystal display panel 10 may be any known transmissive liquid crystal display panel 10. A backlight device 40 is provided below the liquid crystal display panel 10. In addition, when a self-luminous display panel such as an organic EL display panel is used as a display panel, a backlight device...

Abstract

A direct view display device (100A) comprises a display panel (10) having a display region (10A) and a frame region (10F) provided on the outside of the display region, and a translucent cover (20) arranged on the observer side of the display panel. The translucent cover has a lens (22) which is arranged at a position overlapping the region including a part of the frame region of the display panel, and a part of the peripheral display region (10D) in the display region adjacent to a part of the frame region, and is further equipped with a casing (30) having a casing portion (36) arranged at least on the side surface (10b) of the display panel, wherein a portion of the light exiting a part of the peripheral display region and / or the light exiting the back side impinges on the observer-side of the casing portion (36). Thus, a direct view display device equipped with only the display panel wherein the frame is less visible can be provided.

Description

[0001] Technical area [0002] The present invention relates to a display device, especially a direct-view type display device. Background technique [0003] The liquid crystal display device includes a liquid crystal display panel, a backlight device, a circuit and a power supply for supplying various electric signals to the liquid crystal display panel, and a box housing them. The liquid crystal display panel has a display area in which a plurality of pixels are arranged and a frame area around it. Pixel electrodes and TFTs (Thin Film Transistors) are provided in the display area. A sealing part, a drive circuit mounting part, etc. are provided in the frame area. Since pixels are not arranged in the border area, the border area does not contribute to the display. Although the liquid crystal display device is achieving a narrow frame, the frame area cannot be eliminated in principle. [0004] If a large screen is formed by arranging multiple display panels, since the frame area ...
