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.

A color cathode ray tube includes an evacuated envelope having a generally rectangular panel portion, a narrow neck portion having a circular cross-section and a funnel portion tapering down from a panel-portion side thereof toward a neck-portion side thereof for connecting the panel portion and the neck portion, a three-color phosphor screen formed on an inner surface of the panel portion, an electron gun housed in the neck portion, and an internal conductive film extending from an inner wall of the neck portion to an inner wall of the funnel portion. The funnel portion is provided with a yoke-mounting portion of generally truncated quadrilateral-pyramidal shape for mounting a beam deflection yoke therearound on the neck-portion side of the funnel portion. The internal conductive film is formed of a first part and a second part, the first part is formed of graphite, metallic oxide and potassium silicate, and the second part is formed of graphite and potassium silicate. The first part extends from the neck portion in the vicinity of a forward end of the electron gun to a position in the yoke-mounting portion spaced a distance in a range of 60 mm to 150 mm from a splice line between the neck portion and the funnel portion, and the second part overlaps with the first part at opposing ends thereof and extends to a vicinity of a seal line between the funnel portion and the panel portion.
