## Abstract

There is provided a display apparatus including a liquid crystal display having a parallax barrier so that a first image and a second image are respectively visible from different angles on a commonly provided display screen, a backlight that sheds lights from a backside of a liquid crystal panel, a touch operating portion provided at a surface side of the liquid crystal display, and an antiglare layer provided at a surface side of the touch operating portion.

## Claims

### Claim 1

A display apparatus comprising:
a liquid crystal display having a parallax barrier so that a first image and a second image are respectively visible from different angles on a commonly provided display screen;
a backlight that sheds lights from a backside of a liquid crystal panel included in the liquid crystal display;
a touch operating portion provided at a surface side of the liquid crystal display;
an antiglare layer provided at a surface side of the touch operating portion;
a first antireflection layer provided between the parallax barrier and the touch operating portion; and
a second antireflection layer provided between the antiglare layer and the touch operating portion.

### Claim 2 (depends on 1)

The display apparatus as claimed in claim 1, wherein the second antireflection layer prevents reflection of a light having a specific wavelength.

### Claim 3

A display apparatus comprising:
a display controller that outputs to a commonly provided display, output image data that includes at least one of first image data and second image data, the first image data being supplied from a first image source, the second image data being supplied from a second image source;
a liquid crystal display having a parallax barrier so that a first image and a second image are respectively visible from different angles on a commonly provided display screen;
a touch operating portion provided at a surface side of the liquid crystal display;
an antiglare layer provided at a surface side of the touch operating portion;
a first antireflection layer provided between the parallax barrier and the touch operating portion; and
a second antireflection layer provided between the antiglare layer and the touch operating portion.

### Claim 4

A display apparatus comprising:
a display controller that outputs to a commonly provided display, output image data that includes at least one of navigation image data and TV program image data, the navigation image data being supplied from a navigation portion, the TV program image data being supplied from a TV program portion;
a liquid crystal display having a parallax barrier so that a navigation image and a TV program image are respectively visible from a driver's seat and from a front passenger's seat on a commonly provided display screen;
a touch operating portion provided at a surface side of the liquid crystal display;
an antiglare layer provided at a surface side of the touch operating portion;
a first antireflection layer provided between the parallax barrier and the touch operating portion; and
a second antireflection layer provided between the antiglare layer and the touch operating portion.
