Abstract

A display device has a panel having a display, a plurality of light sources and light guiding bodies provided side by side below the rear surface of the panel, and a case having holding spaces provided side by side below the rear surface of the panel, one light source and one light guiding body being placed in each of the plurality of holding spaces. The plurality of light sources selectively emit light so as to selectively display a plurality of indicator patterns at the display. A cover film is integrally formed on the surface of the panel. The upper surface of the case, facing the rear surface of the panel, has a plurality of exposing portions from which the upper ends of the plurality of light guiding bodies are exposed. Each exposing portion has the shape of the indicator pattern in a plan view.

Claims (19)

1 . A display device comprising:

a panel having a display portion;

a plurality of light sources disposed side by side on the same side as a rear surface of the panel;

a plurality of light guiding bodies disposed side by side on the same side as the rear surface of the panel, the plurality of light guiding bodies guiding light emitted from the plurality of light sources toward the display portion of the panel; and

a case having a plurality of spaces disposed side by side on the same side as the rear surface of the panel, one of the plurality of light sources and one of the plurality of light guiding bodies being placed in each of the plurality of spaces, wherein

the plurality of light sources selectively emit the light so that a plurality of indicator patterns are selectively displayed at the display portion,

the panel has a surface on which a cover film is integrally formed,

an upper surface of the case has a plurality of exposing portions from which upper ends of the plurality of light guiding bodies are exposed, and each of the plurality of exposing portions has a shape of one of the plurality of indicator patterns in a plan view, and

the upper surface of the case faces the rear surface of the panel.

2 . The display device according to claim 1 , wherein,

on a rear surface of the cover film, a smoke layer is printed in a first area, which includes the plurality of exposing portions in the plan view, and a light shielding layer is printed in a second area around a periphery of the first area,

a first indicator pattern of the plurality of indicator patterns corresponds to a first source of the plurality of light sources, and the first light source does not emit the light, and

the first indicator is blacked out at the display portion via the smoke layer.

3 . The display device according to claim 2 , wherein,

on the upper surface of the case, a reflection attenuating layer, formed by printing in black or coating in black, is provided in an area facing the first area of the rear surface of the cover film.

4 . The display device according to claim 3 , wherein

the reflection attenuating layer is formed by printing in matte black or coating in matte black.

5 . The display device according to claim 1 , wherein

the case is formed from a white resin having a light shielding property.
