## Abstract

A liquid crystal display panel for displaying images in an active area includes a first substrate having a pair of first short ends and first long ends. A second substrate faces the first substrate so as to hold a liquid crystal layer therebetween. A first polarization plate is arranged on an outside surface of the first substrate. The first polarization plate has a pair of second short ends longer than the first short ends, a pair of second long ends, and a first absorption axis. The angle a1 made by the first absorption axis with respect to the second short ends is smaller than an angle b1 made by the first absorption axis with respect to the second long ends. A second polarization plate is arranged on an outside surface of the second substrate and has a second absorption axis.

## Claims

### Claim 1

A liquid crystal display device, comprising:
a liquid crystal display panel for displaying images in an active area, including;
a first substrate having a pair of first short ends and first long ends,
a second substrate facing the first substrate, and
a liquid crystal layer held between the first substrate and the second substrate,
a first polarization plate arranged on an outside surface of the first substrate having a pair of second short ends longer than the first short ends, a pair of second long ends, and a first absorption axis wherein an angle a1 made by the first absorption axis with respect to the second short ends is smaller than an angle b1 made by the first absorption axis with respect to the second long ends; and
a second polarization plate arranged on an outside surface of the second substrate and having a second absorption axis.
