Abstract

The present invention can include a display device for use in a vehicle having a screen with a polarizing member disposed in the front of a display surface of a liquid crystal display, the polarizing member having a light transmittance of less than 50%, a surface of the screen is coplanar with a surface of the cover member. Also, the polarizing member is not provided on the display surface of the liquid crystal display, and when the liquid crystal display is not used, the screen is inconspicuous, and when the liquid crystal display is used, information can be viewed from the screen.

Claims

1. A liquid crystal display device for vehicle use, which is mounted in place in a vehicle room, and has a liquid crystal display, and a cover member covering the periphery of the liquid crystal display,

characterized in that:

a screen having polarizing means is disposed in the front of a display surface of the liquid crystal display, the polarizing means having a light transmittance of less than 50%,

a surface of the screen is in the same level as a surface of the cover member,

the polarizing means is not provided on the display surface of the liquid crystal display, and

when the liquid crystal display is not used, the screen is inconspicuous, and when the liquid crystal display is used, various kinds of display information can be viewed via the screen.

2. The liquid crystal display device for vehicle use according to claim 1:

wherein

the screen is a sheet-like member having a shape retaining property, and

the screen has a deflection function.

3. The liquid crystal display device for vehicle use according to claim 1:

wherein

the screen has transparent protective layers disposed on two sides of a polarizing film, and

has an antireflective layer at a surface side of the screen.

4. The liquid crystal display device for vehicle use according to claim 1:

wherein

the screen is formed in a two-dimensionally or three-dimensionally curved shape in accordance with a surface profile of the cover member.

5. The liquid crystal display device for vehicle use according to claim 1:

wherein

an anti-see-through portion is formed in an outer circumferential edge portion of the screen, and

the screen integrally has a display region in a central portion, and an anti-see-through portion enclosing the whole circumference of the display region.

6. The liquid crystal display device for vehicle use according to claim 5:

wherein

area of the display region is approximately the same as area of the display surface of the liquid crystal display.

7. The liquid crystal display device for vehicle use according to claim 6:

wherein

the screen has the anti-see-through portion formed in the outer circumferential edge portion of the screen, in addition, has an anti-see-through portion in a horizontal direction formed at a vertically lower part, and
