Abstract
Official abstract text for this publication.
A display apparatus includes a display panel disposed between a first polarizer and a second polarizer and having at least one first area and at least one second area. A first light-transmission axis direction of the first polarizer is substantially perpendicular to a second light-transmission axis direction of the second polarizer. The first light-transmission axis direction intersects a horizontal axis direction by about 45 degrees. When the display panel is in a narrow viewing angle display mode, the first and second areas have different brightness in a side viewing angle direction but have the same brightness in and around a normal viewing angle direction. When the display panel is in a wide viewing angle display mode, the first and second areas have substantially the same brightness in various viewing angle directions.
