Abstract
An in-plane switching (IPS) mode liquid crystal display (LCD) device includes a liquid crystal display panel having a first substrate, a second substrate, and a liquid crystal layer between the first and second substrates; a second polarizer on an outer surface of the second substrate, the second polarizer having a second polarizing element; and an in-cell retarder on an inner surface of the second substrate, wherein the in-cell retarder compensates a light leakage in a front direction of the liquid crystal display panel.
Claims19
A display device, comprising:
- a liquid crystal display panel having a first substrate, a second substrate, and a liquid crystal layer between the first and second substrates;
- a second polarizer on an outer surface of the second substrate, the second polarizer having a second polarizing element;
- and
- at least two optical compensation films between the color filter substrate and the second polarizing element to enhance a viewing angle in a diagonal direction of the liquid crystal display panel, the at least two optical compensation films including a positive biaxial film and a negative biaxial film in consideration of a polarization state of the liquid crystal layer.
