Provided is a liquid crystal display device including a liquid crystal display panel, a fluorescent tube, a holder for retaining the fluorescent tube, and a frame to which the holder is attached. The holder includes an attachment portion for attaching to the frame, and a retaining portion for the fluorescent tube, the retaining portion extending from the attachment portion and facing the frame in a non-contact manner. The retaining portion and the frame have a space formed therebetween.

Provided is a liquid crystal display device in which uneven brightness in a side-light type backlight unit is reduced, the uneven brightness being generated through reflection of light from a light source at an interface of an engaging cutout portion for preventing a light guide plate from shifting. A light guide plate () includes a cutout portion () through which a light guide plate support pin () provided upright to a lower frame fitting is inserted, at a lower side adjacent to a left side at which a light bar () is arranged. Further, at the lower side, a cutout portion () having a shallower recess than that of the cutout portion () and positioned in front of the cutout portion () when viewed from the light bar () is provided.

A reflection sheet is made of material having a coefficient of thermal expansion different from that of an LED substrate. A fixing member and a retaining member extend through the reflection sheet and the LED substrate so as to fix the reflection sheet and the LED substrate. The reflection sheet includes a fixing hole into which the fixing member is inserted, a retaining hole into which the retaining member is inserted, and LED holes within which light emitting diodes are disposed, respectively. Retaining of the reflection sheet by the retaining member has, compared to fixing of the reflection sheet by the fixing member, a higher degree of freedom of movement in a direction along a surface of the reflection sheet. The LED holes located in positions far from the fixing hole are larger than the LED holes located in positions close to the fixing hole.

The present invention prevents the corrosion of a printed circuit board which is connected to a lower side of a display panel in a liquid crystal display panel. In a display device which includes a display panel and a frame member which supports an outer peripheral portion of a display screen of a display panel, a water absorbing member is adhered to a surface of the frame member which faces the display panel in an opposed manner.

The present invention provides a liquid crystal display device which reduces the occurrence of a squeal. A liquid crystal display device includes a liquid crystal display panel and a backlight arranged on a back surface of the liquid crystal display panel, wherein the backlight includes a base, a plurality of rod-shaped light sources arranged between the liquid crystal display panel and the base, electrode fittings for supporting electrode portions of the respective rod-shaped light sources, connection portions allowing the plurality of electrode fittings to be connected thereto and extending in the direction orthogonal to the longitudinal direction of the rod-shaped light sources, pushing members for pushing the connection portions toward a base side, and friction sound reducing members arranged between the connection portions and the pushing members and/or between the connection portions and the base side.
