摘要： An optical sheet includes a first plane, a second plane facing the first plane and a plurality of optical patterns. The optical patterns are formed on the second plane along a plurality of columns. An optical pattern includes a plurality of convex light-condensing portions. End portions of the light-condensing portions are connected to each other continuously and form crests and troughs. The optical patterns disposed in adjacent columns share a common side.

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.

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： Disclosed are a prism sheet and a liquid crystal display having the same. The prism sheet includes a base and a plurality of prism mountains. The base includes a front surface and a rear surface facing the front surface. The prism mountains are integrally formed with the base on the rear surface of the base. At least one prism mountain includes a plurality of light incidence surfaces and a reflective surface. The light incidence surfaces receive light. The reflective surface is adjacent to one of the light incidence surfaces to reflect the light. A vertical angle of the prism mountains formed between the light incidence surface adjacent to the reflective surface and the reflective surface, is in a range of about 70° to about 100°.
