Description

[Detailed description of the invention] Industrial applications The present invention relates to a display device having a liquid crystal display panel.

Conventional technology Conventionally, a frame body was provided that held a liquid crystal display panel on the front and the back side was open toward the light source, and multiple angle pieces were connected in a parallel cross shape to form a support shelf, and the frame was surrounded by the angle pieces. The frames are fixed with rear openings of the frames facing each of the plurality of openings, and light from a light source is irradiated from the openings of the support shelf into the inside of the frame to display the liquid crystal display board. There are display devices that display images by illuminating and controlling individual liquid crystal display elements.

Problems to be Solved by the Invention However, since the front side of the angle member is not irradiated with light from the light source, there is a problem in that the shadow of the angle member is reflected on the liquid crystal display panel.

The present invention has been made in view of these points, and an object of the present invention is to provide a display device that illuminates the front surface of a liquid crystal display panel with uniform brightness.

Means for Solving the Problems A frame body for holding a liquid crystal display board and a support shelf formed by joining a plurality of angle members in a grid shape are provided, and the frame member is placed in an opening surrounded by the angle members. This frame body is fixed to a support shelf with rear openings facing each other, a holding part for holding the rear part of the frame body is provided on the front surface of the angle material, and a reflection member is provided on the front surface of the angle material to reflect the light beam of the light source. Fix the board.

Effect: Therefore, the reflector plate located on the front side of the angle member reflects the light rays from the light source and shines. This prevents the shadow of the angle material from appearing on the liquid crystal display panel.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 and 2. Reference numeral 1 denotes a frame whose back side is open, and a liquid crystal display board 4 in which a plurality of liquid crystal display elements 2 are fixed to a transparent panel 3 is held on the front side of the frame 1. A groove 5 with an opening at the rear end is formed on both side surfaces of the frame body 1. Note that a reflective surface is formed on the inner surface of the frame 1.

A support shelf 6 is then provided. This support shelf 6 is formed by connecting a plurality of angle members 7 having an L-shaped cross section in a cross-section shape. A plurality of openings 8 surrounded by these angle members 7 face the rear opening of the frame 1. The angle members 7 arranged in the vertical direction have a holding part 9 that protrudes from the boundary between two adjacent frames 1 and is fixedly fitted into the groove 5.
is fixed. Further, a reflecting plate 10 located around the opening 8 is fixed to the angle member 7. Reflector 1
0 is formed by bending a metal plate into a triangular cylindrical shape, and a hole 11 from which a holding part 9 protrudes is formed at the top of a reflecting plate IQ fixed to vertically arranged angle members 7.

A plurality of light sources 12 are arranged on the back surface of the support shelf 6.

In such a configuration, a light beam from the light source 12 is irradiated into the frame 1 through the opening 8 to illuminate the liquid crystal display panel 4,
The individual liquid crystal display elements 2 of the liquid crystal display panel 4 are controlled to display images. At this time, the reflection plate 10 fixed to the front surface of the angle material 7 receives the light from the light source 12 and shines, so that the shadow of the angle material 7 is not reflected on the front surface of the liquid crystal display panel 4, and the brightness of the entire surface is uniform. can do.

In addition, as shown in FIG.
3 may be provided, and a plurality of reflectors 14 may be arranged vertically with the notches 13 facing each other and fixed to the angle members 7 arranged in the vertical direction.

The hole with the two notches 13 facing each other is the hole 10 of the long reflector 10.
Similarly, the holding portion 9 will be made to protrude.

Effects of the Invention Since the present invention is configured as described above, the reflection plate located in front of the angle material reflects the light rays from the light source and shines, so that the shadow of the angle material is not reflected on the liquid crystal display board. This has the effect of making the brightness of the liquid crystal display panel uniform.
