Abstract: 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.

Abstract: An optical module includes a point light source device and an optical lens. The point light source device generates light. The optical lens includes an inner curved surface and an outer curved surface. The inner curved surface has a first roughly ellipsoidal shape having a first major axis and a first minor axis that is substantially perpendicular to the first major axis. The outer curved surface has a second roughly ellipsoidal shape having a second major axis that is substantially perpendicular to the first axis and the second minor axis that is substantially perpendicular to the second major axis. The light generated by the point light source device enters the optical lens through the inner curved surface and exits from the optical lens through the outer curved surface. Therefore, the number of optical modules used in a display device may be reduced to lower manufacturing cost thereof.

Abstract: A light guide plate that eliminates haze while obtaining a desired uniformity of luminance to enhance light efficiency. The light guide plate can be used with a backlight unit using the light guide plate and an LCD using the backlight unit. The light guide plate includes an incidence face to allow light emitted from a light source to be incident to the light guide plate, an outgoing face to allow the incident light to exit the light guide plate, a backside face opposite to the outgoing face, and mirror patterns provided at the outgoing face or backside face, and adapted to increase an exiting rate of the light at a low luminance region defined in a vicinity of the light source.

Abstract: A backlight assembly includes a receiving container having a receiving space, a flat-type light source, an optical member, and an inverter. The flat-type light source has a plurality of light emitting spaces spaced apart from each other and is received into the receiving space.
