摘要： A back light unit, in which bright lines produced from point light sources, light emitting diodes, in an oblique direction are removed, so that brightness can be uniformly maintained at a liquid crystal panel. The back light unit includes a prism light guide plate, light emitting diodes provided on one side of the prism light guide plate, and a bright-line dead section provided to the prism light guide plate so as to uniformly scatter light of each light condensing section generated by light emitted from the light emitting diodes, to prevent a spectrum of the light in a specific direction, and to prevent bright lines from being produced.

摘要： 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. The light guide plate is manufactured by a method including a mold machining operation including a prism face milling operation to form, at a mold, a prism face corresponding to a prism face of the light guide plate, and a mirror pattern milling operation to mill the prism face formed at the prism face milling operation using a bit having a predetermined cross-sectional shape, thereby forming mirror patterns at the prism face, and a light guide plate injection-molding operation to mill a molten resin into the mold completely machined at the mold machining operation, thereby injection-molding the light guide plate.

摘要： 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.
