Abstract: Backlight with which the uniformity of brightness within a display area of a concavely curved liquid crystal display device is improved while fulfilling the demand for slimmer liquid-crystal display devices, as well as curved liquid-crystal display device including such a backlight. The shape of a frame, an optical sheet, and a scattering plate constituting the backlight unit is the same concavely curved shape as that of the concavely curved panel; and the liquid-crystal panel, the optical sheet, and cold-cathode luminescent lamps are arranged such that the concavely curved panel, the surface of a frame constituting the backlight unit that faces the concavely curved panel, an optical sheet surface, and a surface including the tube center axes of a plurality of cold-cathode luminescent lamps are parallel to each other.

Abstract: Liquid-crystal display device with a concavely curved panel in which a reflective plate is installed with which a uniform brightness of the screen of the liquid-crystal device with curved screen can be maintained and brightness non-uniformities can be remedied, without making the outer shape of the liquid-crystal display device large. In a liquid-crystal display device having a structure in which a concavely curved panel is held by spacers having a curved shape that are installed on a backlight unit, a reflective plate or reflective sheet is attached to all those inner walls formed by an inner space enclosed by the concavely curved panel, the spacers and the backlight unit that are formed by components that are installed between the curved panel and the backlight unit and that are formed by components that are not transmissive to light that is emitted from the light source.

Abstract: Curved-panel liquid crystal display and method of its manufacture are realized without necessitating drastic changes to the display structure or to the steps in its manufacture, and without requiring new materials or manufacturing technology. The back side of a liquid crystal panel is set on first concavely curved spacers that support two opposing edges of the panel back side. Second concavely curved spacers are set on the front side of the two opposing panel edges. Third spacers of uniform height are disposed on the panel back side to support it along the remaining two edges. The second spacers are then pressed to pressure the panel from the front side against the first spacers, wherein the panel is clamped between the first and second spacers.

Abstract: A liquid-crystal display device includes a liquid-crystal display panel having a liquid-crystal layer sandwiched between a pair of substrates, and a backlight unit provided on a surface opposite to a display surface of the liquid-crystal display panel. The backlight unit has an accommodator capable of having at least one optical sheet arranged therein and having a sidewall having a projection at a periphery thereof. The optical sheet has a hole into which the projection is inserted, the hole formed in the optical sheet having a form that is the same as the top plan form of the tip of the projection, the hole being formed in the optical sheet so that a certain rotation angle is established between the form of the hole and a top plan form of the tip of the projection in a state in which the optical sheet is accommodated in the accommodator.

Abstract: Disclosed herein is a casing assembly for a display device. The casing assembly includes a rear casing and a front casing. The rear casing includes a middle part with an H-shaped section, the H-shaped part is provided with an upward recess for receiving a display unit and a downward recess for receiving a circuit module. The front casing is provided with an opening to expose a display panel of the display unit. The front casing and the rear casing are connected together with plug-in connecting means. The casing assembly of the present invention makes it possible to cut down the number of components of the display device as well as the steps of the assembly process. Also disclosed herein is a display device which is provided with the casing assembly of the present invention.

Abstract: Optical sheets can be fixed easily and positively in a liquid-crystal display device having a liquid-crystal display panel in which a liquid-crystal layer sandwiched between a pair of substrates and a lighting unit provided on a surface opposite to a display surface of the liquid-crystal display panel. For this purpose, a projection is provided on a sidewall of an accommodator, and the projection is inserted into a hole provided in optical sheets arranged within the accommodator, thereby fixing the optical sheets in the accommodator. The length along a certain straight line of a top plan form of a tip of the projection is longer than the length along the certain straight line of the hole formed in the optical sheets, thus preventing the optical sheets from falling out of the accommodator.
