DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device for automobiles and the like.

Generally, a display device is provided that centrally informs the driver of the failure location of each part of the vehicle or the operating status of various devices.

A general display device of this type will be explained using FIG. Reference numeral 1 denotes a housing made of synthetic resin or the like that is attached to an appropriate position on an instrument panel of a vehicle, and this housing 1 is provided with a partition wall 1A that partitions each room. Further, a lamp 2 is installed at the bottom of each room separated by the partition wall 1A of the housing 1, facing inward of the housing 1, and a display board 3 is installed on the surface side of each room of the housing 1. .

The display board 3 is made of a transparent synthetic resin such as polycarbonate resin, acrylic resin, or AS resin, and the back side of the display board 3 is coated with light-shielding ink, etc. to display various objects on the vehicle. It is formed by cutting out and printing an item such as display character 4. Further, a colored lens 5 is interposed below the display characters 4 on the display board 3. Further, the colored lens 5 is diamond-cut to form a display irradiation surface 5A having an uneven lens surface, and the display irradiation surface 5A refracts and reflects, or diffuses and condenses, the light rays of the lamp 2 for display. The display characters 4 on the board 3 are irradiated, and the amount of light that emerges on the front side of the display characters 4 differs depending on each location, and it shines in a three-dimensional manner just like the shape of the diamond cut, and the light on the display board 3 surface This ensures good readability from the beginning.

However, when manufacturing the display illumination surface 5A of the uneven lens surface formed on the colored lens 5 by diamond cut processing, etc., the mold for forming the colored lens 5 becomes complicated, requiring time and effort to manufacture, and the mold cost is high. There are several factors that can be cited.

This point should be taken into consideration, for example,
- As disclosed in Publication No. 13577, etc., there was a display board printed in a mesh pattern with a colored part that does not allow light to pass through and a transparent part that allows light to pass through. Proposed.

However, the patterned area, such as a mesh pattern, is a pattern consisting of an opaque area and a transparent area, and since the opaque area blocks the light, the amount of light is likely to decrease, resulting in transmitted illumination due to mere cut-out printing. There is a problem in that it is not possible to produce a lighting effect with a three-dimensional sense of depth.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a display device that can provide a three-dimensional lighting effect by simplifying the configuration of the display device.
