A display apparatus used for creating 3D images has a display panel and a phase-delaying layer disposed on the display panel. The phase-delaying layer has first and second light-changing patterns that are self-aligned to at least one of pixels and a black matrix of the display panel. The self-aligned structure is formed by selectively passing curing light (e.g., UV light) through the display panel to cure curable liquid crystal films while the films are respectively aligned by aligning layers having different alignments.

A display apparatus including a first insulating substrate, a plurality of pixels, a second insulating substrate, a color filter layer, and a pattern retarder. The first insulating substrate includes a plurality of pixel areas arranged in an array of rows and columns, which has a length in the row direction longer than a length in the column direction, and has a length in a row direction longer than a length in a column direction. The pixels are arranged in the pixel areas, respectively, to display a 2D image and a 3D image. Among the pixels, first to fourth pixels successively arranged in the column direction define a unit pixel that displays one color information, and the fourth pixel corresponds to the white color pixel.

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.
