摘要： A liquid crystal display capable of improving display quality while achieving a reduction in manufacturing cost. The liquid crystal display includes a liquid crystal panel having multiple pixels arranged at a first pitch; a light source for supplying light to the liquid crystal panel; and a light guide plate for guiding the light to the liquid crystal panel, wherein prisms are formed on the light guide plate at a second pitch, the second pitch is the sum of a quotient and a corrected value, the quotient is obtained by dividing the first pitch by a natural number m, the corrected value depends on a selected viewing distance and an interval between the liquid crystal panel and the prisms.

摘要： A backlight assembly includes a light source, a light-guide plate (LGP), a reflective sheet and at least one optical sheet. The light source emits light. The LGP includes a light-incident surface, a light-reflecting surface and a light-emitting surface. The light-incident surface receives the light from the light source. The light-reflecting surface has a plurality of first prism patterns spaced apart from each other and flat portions formed between the first prism patterns, which are substantially perpendicular to the light-incident surface. The light-emitting surface has a plurality of second prism patterns formed thereon. The reflective sheet is disposed below the LGP. At least one optical sheet is disposed on the LGP.

摘要： A light-guide plate (LGP) includes a light-incident surface, a light-facing surface, a light-emitting surface and a light-reflecting surface. The light-incident surface receives light. The light-facing surface has a smaller size than that of the light-incident surface. The light-facing surface faces the light-incident surface. The light-emitting surface is extended substantially perpendicular to the upper side of the light-incident surface. The light-emitting surface is connected to the upper edge of the light-facing surface. The light-reflecting surface has a plurality of first prism patterns that are formed parallel with the light-incident surface. The light-reflecting surface is extended from the base of the light-incident surface to be connected to the base of the light-facing surface. Therefore, a leakage of light that exits from the wedge-type LGP through a side surface of the wedge-type LGP is decreased, so that luminance is enhanced.

摘要： A light-diffusing member includes a first face, a second face arranged opposite to the first face, and a light-diffusing portion including at least one valley and at least one ridge that are alternatively arranged. A first thickness of the light-diffusing member between the ridge and the first face is about 1.15 to about 1.80 times greater than a second thickness of the light-diffusing member between the valley and the first face.

摘要： A compact, light, and uniformly bright backlight assembly and a display device are disclosed. The backlight assembly includes a light source assembly, a substrate, and a transflective member. The light source assembly emits a first light with a first luminance uniformity. Then, the first light passes through the substrate above the light source assembly for producing enhanced luminance uniformity. Again, after the light is reflected from and/or transmitted through the transflective member, the luminance uniformity is even more enhanced. Therefore, the volume, weight, and luminance uniformity of the backlight assembly and the display device are enhanced.
