Abstract: There are provided a light-source device which is capable of restraining deformation of side walls of a housing due to heat generated by the light emission of the light source, and a display apparatus. A light-source device is provided with a light guide plate which is placed on a bottom plate of a housing having an opening formed at one surface thereof, and a light source which is fixed to the housing and is arranged to face one end face of the light guide plate, and the bottom plate of the housing has a separation part that separates the bottom plate into a first portion in which the light source is disposed and a second portion in which the light source is not disposed.

Abstract: The present invention provides a display apparatus capable of reliably mounting at least one of a holding member and a bezel to a holding plate with no damage to a light emitting element mounting substrate by a simple structure without providing a mounting member, and coping with an increase in an area of a driving circuit board disposed to the holding member. The display module of a TV receiving apparatus includes a light guide plate, a holding plate which holds a substrate having a plurality of LEDs, and is disposed to face a side surface of the light guide plate, a display panel disposed to face a main surface of the light guide plate, a holding member which covers the holding plate and holds the display panel, and a bezel which covers a peripheral edge part of the display panel and the holding member.

Abstract: Provided is a display apparatus in which a deflection of an optical sheet as well as a slit due to vibration and impact are suppressed while a flaw in a member being in contact with the optical sheet is suppressed, uniform surface luminance and preferable image quality are attained, and thus the occurrence of a defect is suppressed. A display module in a TV receiver includes a display panel, an optical sheet group, a light guide plate, a chassis, a panel holding member and a bezel. At the middle part of the lower side portion of the optical sheet group, a latch hole is formed. At a portion of the bottom part of the chassis, which is opposed to the latch hole, is provided with a projecting part formed to have a cylindrical main body and a latch projection continuously formed from the main body with a cylindrical shape having a diameter smaller than that of the main body.

Abstract: A lighting device used as a backlight of a display apparatus includes multiple light guide plates, and a light source located near an entrance edge of each light guide plate to emit light. A gap is provided between the light guide plates, and the position of the entrance edge is fixed among the edges of the light guide plate. If the light guide plates are expanded in accordance with a change in temperature or humidity, the entrance edge do not move while the light guide plates are expanded so as to approach each other. Since the light guide plate does not hit the light source and the amount of expansion of the light guide plates is absorbed into the gap, the light source may be arranged as close as possible to the entrance edge of the light guide plate in the lighting device.

Abstract: A display apparatus includes: a display panel displaying an image; a light guide plate facing the display panel. The display panel and the light guide plate are coupled by a coupling member disposed at a peripheral portion of the display apparatus, and an optical sheet being interposed in a void formed between the display panel and the light guide plate. The coupling member includes a leg plate having a strip shape and two side plates protruding inward from both edges in a width direction of the leg plate approximately in parallel to each other. The coupling member is attached in such a way that the leg plate is provided along both a peripheral edge of the display panel and a peripheral edge of the light guide plate, one of the two side plates extending inward is provided along a facing surface of the display panel facing the light guide plate, and the other of the two side plates is provided along at least one surface of the light guide plate.

Abstract: Provided is a display apparatus capable of preventing the warp and the optical leak of an optical sheet. The display apparatus includes: a display panel which displays an image; a light guide plate which faces the display panel and emits light towards the display panel; a spacer which forms a gap between the light guide plate and the display panel; and an optical sheet arranged at the gap. A peripheral portion of the light guide plate is located outside with respect to the display panel, and the spacer includes a panel attaching part which is attached at an edge portion of one surface of the display panel and with a light-guide-plate attaching part which continues to the panel attaching part and is attached at an edge portion in one surface of the light guide plate.

Abstract: Provided are an illumination device and a display device capable of even illumination. A positioning recess provided in a light guide plate and a peripheral portion of the recess are covered by a cover from one surface side of the light guide plate. As a result, the cover suppresses the emission of light emitted from the vicinity of the recess on the one surface of the light guide plate onto the outside of a backlight unit that functions as an illumination device. Thus, even if light is scattered at the recess of the light guide plate and the brightness of the vicinity of the recess is greater than the brightness of other portions, the leaking of excessively bright light onto the outside of the backlight unit (in this case, onto the display panel side) is suppressed. That is, brightness unevenness caused by the recess of the light guide plate is suppressed.
