Abstract
A display panel includes a first substrate, a second substrate, a liquid crystal layer, a first polarizer, a second polarizer and a viewing angle control layer. The second substrate faces the first substrate. A liquid crystal layer is disposed between the first substrate and the second substrate. A first polarizer is disposed on a lower surface of the first substrate and includes a first polarizing layer and a second polarizing layer stacked on each other. A second polarizer is disposed on an upper surface of the second substrate. A viewing angle control layer is disposed on the first polarizer and is configured to control a viewing angle of a column direction of the display panel.
