Abstract: A liquid crystal display device (1), comprising a liquid crystal display panel and an illumination unit (10). The illumination unit (10) further comprises a housing (11) having a rectangular bottom wall face and having, at its side peripheral edge parts, cut and erected pieces (141) and (142) formed by cutting out a part of the bottom wall surface and projecting the cutout parts to the rear surface, and a frame-shaped intermediate frame (20) having a display window (200) at its center part to which an illuminating member stored in the housing (11) is fixed. The intermediate frame (20) comprises locking pieces (231) inserted into opening parts (140) formed, when the cut and erected pieces are cut and raised, at positions corresponding to the cut and erected pieces (141) and (142).

Abstract: A lighting unit and a liquid crystal display unit using this, comprising a housing having a rectangular bottom wall surface and formed respectively at a pair of facing side edges thereof with locking projections projecting from the bottom wall surface, a reflection sheet having locking portions locked with the respective locking projections, and a light guide plate laminated on the reflection sheet and having locking portions locked with the locking projections, wherein the locking projections are formed on the center lines X-X connecting the center points of the sides, where no light sources are formed, of the light guide plate, and the locking portions of the reflection sheet and the light guide plate are locked with these locking projections and fixed, thereby providing a lighting unit having the reflection sheet fixed so as to be wrinkle-free, and a liquid crystal display unit using this.

Abstract: When viewed from the end face side of a light guide plate, all linear lamps in a backlight may be arranged to be able to be viewed directly without being intercepted by other lamps and supported by a spacer. A lamp reflector may have a back surface facing the plurality of linear lamps, and a side face for supporting the back surface against the light guide plate, wherein the back surface may have a reflective surface projecting inward at the central part along the longitudinal direction of the reflector. Luminance of the light guide plate may be enhanced by utilizing lights exiting the linear lamps efficiently in the backlight of a large liquid crystal display, appropriate intervals may be sustained among the plurality of linear lamps, and luminance lowering due to high frequency interference caused by a contact of each linear lamp with a reflector may be prevented.

Abstract: In a display module having a picture-frame-shaped front frame, notches are formed at both ends of one side edge thereof so as to penetrate from the front surface to the rear surface thereof. This helps realize a compact display unit. Moreover, a metal film or the like is formed on a flexible printed circuit used in the display module, and the flexible printed circuit is fixed to a metal rear casing with a detachable protective plate. This helps realize a display module that permits easy attachment and detachment of a flexible printed circuit and in which sufficient shielding against EMI (the metal film is grounded via the rear casing) is achieved.
