摘要： A polarizing plate includes a base substrate, a conductive lattice pattern and a light absorbing pattern. The base substrate has a first surface and a second surface located opposite to the first surface. The conductive lattice pattern is formed on the first surface in a stripe arrangement. The conductive lattice pattern reflects and/or polarizes light incident on the conductive lattice pattern. The light absorbing pattern is formed on the first surface and corresponds to the conductive lattice pattern. The light absorbing pattern absorbs at least a portion of light reflected on an arbitrary interface after being polarized by the conductive lattice pattern. Thus, an undesired polarization component of a light exiting through a polarizing plate may be reduced, thereby increasing a contrast ratio of a display panel.

摘要： An optical unit includes a base, a light-condensing member disposed on the base to condense a first portion of light that is incident onto the base and protrusion members disposed on a surface of the light-condensing member to scatter a second portion of the light that is incident onto the base. A backlight assembly includes light sources, an optical unit receiving light from the light sources to condense and scatter the light, and may also include an optical member disposed over the optical unit to enhance the front luminance of the light. A display device includes light sources, an optical module and a display panel. Thus, display quality of the display device may be enhanced.

摘要： A light-condensing member includes a base plate, a main light-condensing pattern formed on the base plate, and a sub light-condensing pattern formed on the main light-condensing pattern. The main light-condensing pattern includes a plurality of main prisms extended in a first direction. A cross section of a main prism taken along a second direction substantially perpendicular to the first direction has a substantially triangular shape. The sub light-condensing pattern includes a plurality of sub prisms formed on the main prisms and extended in a second direction substantially perpendicular to the first direction. A cross section of a sub prism taken along the first direction has a substantially triangular shape. Since light is condensed simultaneously in both a horizontal direction and a vertical direction through one light-condensing member, manufacturing costs and the thickness of backlight assembly are reduced.
