Abstract

Provided is a technique allowing a screen of a display device to be harmonized with a housing of the display device or an environment surrounding the display device, while an image is not displayed. A display device ( 1 ) includes: a display section ( 2 ) which displays an image; and a background section ( 3 ) which is provided on a front surface side of the display section ( 2 ), the background section ( 3 ) having a plurality of openings ( 4 ) through which light, emitted from the display section ( 2 ) for display of the image, passes.

First claim

1 . A display device comprising:
a display section which displays an image; and a background section which is provided on a front surface side of the display section, the background section having a plurality of openings through which light, emitted from the display section for display of the image, passes.

2 . The display device as set forth in claim 1 , wherein each of the plurality of openings is provided for a corresponding one of pixels which are included in the display section, for a corresponding one of picture elements which constitute each of the pixels, or for corresponding adjacent ones of the pixels.

3 . The display device as set forth in claim 2 , wherein a ratio of an area of the each of the plurality of openings to an area of the corresponding one of the pixels which are included in the display section, the corresponding one of the picture elements which constitute the each of the pixels, or the corresponding adjacent ones of the pixels is 10% to 15%.

4 . The display device as set forth in claim 1 , wherein a brightness ratio B r is not less than 3.5, the brightness ratio B r being calculated by the following Expression (A):
B r =( B d −B n )/ B n   (A)
where: B d represents a brightness while the display section displays the image, the brightness including both (i) a brightness of the image which is displayed by the display section and which has passed through the plurality of openings formed in the background section and (ii) a brightness of a surface of the background section which brightness is based on external light; and B n represents the brightness of the surface of the background section which brightness is based on the external light, while the display section does not display the image.

5 . The display device as set forth in claim 1 , wherein a front surface, other than the plurality of openings, of the background section is decorated.

6 . The display device as set forth in claim 1 , further comprising a touch panel which is provided between the background section and the display section.

7 . The display device as set forth in claim 1 , wherein each of the display section and the background section is bendable.

8 . The display device as set forth in claim 7 , wherein the display section is an organic EL display or a reflective liquid crystal display.

9 . The display device as set forth in claim 1 , wherein each of the display section and the background section has a circular shape, an elliptical shape, a trapezoidal shape, a curved shape, a hemispherical shape, or a spherical shape.

10 . The display device as set forth in claim 1 , wherein:
the background section is a decorated film; and the decorated film has, as the plurality of openings, holes which pass through the decorated film.

11 . The display device as set forth in claim 1 , wherein:
the background section includes a transparent substrate and a decorated film which is provided on the transparent substrate; and the decorated film has, as the plurality of openings, holes which pass through the decorated film.

12 . The display device as set forth in claim 1 , wherein:
the background section includes a transparent glass substrate and a decorated film which is provided on the transparent glass substrate; and the decorated film has, as the plurality of openings, holes which pass through the decorated film.

13 . The display device as set forth in claim 1 , wherein:
the background section is a resin layer which is obtained by coating a decorated film with a transparent resin; and the decorated film has, as the plurality of openings, holes which pass through the decorated film.

14 . The display device as set forth in claim 1 , wherein:
the background section is a decorated glass; and the decorated glass has, as the plurality of openings, a non-decorated part through which the light, emitted from the display section for the display of the image, passes.
