摘要:
A backlight unit a light source for originating light; a light guide plate including incident portions through which light originated form the light source enters and an emitting portion form emitting the entered light; and a chassis including a first recessed portion having a first depth and on which the light source is located and a second recessed portion having a second depth deeper than the first depth and a sice adjusted for the light guide plate and on which the light guide plate is located.

An object of the invention is to make a light source and a power supply line detachable easily so as to enable the light source to be replaced easily for maintenance. The invention provides a lighting device for a display, which includes a light source having electrode terminals provided at both ends thereof, connectors attached to the ends of a power supply line for supplying power to the light source, light source-holding chassis placed at the ends of the light source, and insertion portions opened in the chassis. The electrode terminals of the light source are placed inside the insertion portions, and the connectors are fitted detachably in the insertion portions from the outside, whereby the terminals in the connectors are connected to the electrode terminals.

In a light source holding device holding a cold cathode tube (linear light source) by clamping it between first and second claws, the first and second claws are provided in such a manner that they are in contact with the cold cathode tube while being displaced in position in the longitudinal direction of the cold cathode tube. Consequently, degradation in display quality can be prevented.

A display device includes a plurality of cold cathode tubes that define linear light sources and are arranged in an aligned state in a backlight device. A direction that is perpendicular or substantially perpendicular to a surface S along the direction of alignment of the cold cathode tubes is set as the illumination direction. The cold cathode tubes are supported in two kinds of postures whose axes intersect with each other. A first inclined cold cathode tube and a second inclined cold cathode tube are arranged in postures that incline the axis of each relative to the direction of illumination. The overall distribution of light intensity can be expanded by the amount of the relative inclination angles of the first inclined cold cathode tube and the second inclined cold cathode tube.

An illuminating apparatus for a displaying apparatus has a clearance C provided between an end edge of a reflective sheet and a base part of a rubber holder which is located on the outer edge of the reflective sheet and closely fixed to the bottom plate part. In addition, the clearance C is set between the hole edge of the mounting hole and the supporting base part of the lamp clip, around the mounting hole. Therefore, expansion deformation of the reflective sheet in the sheet surface direction due to thermal expansion and variation of dimensions due to mold tolerance can be absorbed by the clearances C. As a result, deflection and curling of the reflective sheet is reliably prevented.

To provide a chassis for a light source unit, a light source unit including the chassis, and a display device including the chassis, the chassis being capable of holding a light source placed on the chassis so as to prevent the light source from falling off the chassis without attaching side holders to the chassis. A backlight chassis 11, on a wall surface of which the light source 12 is to be placed, includes holding members 111a and 112a arranged to hold a holder 121a attached to the end of the light source 12 so that the light source 12 does not easily fall off the backlight chassis 11.
