    Abstract: A display device includes a lens with an adjustable refractive index. The display device includes a display panel including a plurality of pixels, a backlight unit positioned at a back side of the display panel to emit light of a first color and light of a second color to the display panel at different times, the first color and the second color being different from each other; and a lens unit positioned at a front side of the display panel to form at least one lens in a 3D mode. The lens unit includes a plurality of electrodes for adjusting a refractive index of the lens, and a signal applied to the electrodes when the backlight unit emits the light of the first color is different from a signal applied to the electrodes when the backlight unit emits the light of the second color.

    Abstract: A flat panel display device is provided with an increased viewing angle having good dark versus light imaging contrast. The display device includes a display panel, a first optical unit, and a second optical unit. The display panel includes a liquid crystal layer that is driven in a vertical alignment mode. The first optical unit includes a negative C-plate and a first polarizer having a first absorption axis. The second optical unit includes a biaxial compensation plate having a refractive indices coefficient, (nx−nz)/(nx−ny) of more than 0.45 and less than 0.55, and a second polarizer having a second absorption axis crossing the first absorption axis. The biaxial compensation plate has a refractive indices relationship of nx>nz>ny such that dispersion of polarization states of colored light rays passed through the C-plate and the liquid crystal layer may be minimized and gathered about an extinction point, thereby improving contrast at side viewing angles.

    Abstract: A display apparatus comprises a display panel, a first polarizing plate and a second polarizing plate. The display panel comprises a first substrate including a pixel electrode, a second substrate opposite to the first substrate, and a liquid crystal layer disposed between a first surface of the first substrate and a first surface of the second substrate. The first polarizing plate comprises a first polarizer having a first polarizing axis, and a first λ/4 phase difference plate having a refractive index between about 1.35 and about 2.05 in a thickness direction. The second polarizing plate comprises a second polarizer having a second polarizing axis crossing the first polarizing axis, and a second λ/4 phase difference plate having a refractive index between about 1.35 and about 2.05 in a thickness direction. Accordingly, light leakage in a side view may be reduced and viewing angle may be improved.
