ILLUMINATING DEVICE, DISPLAY DEVICE AND TELEVISION RECEIVER

摘要

An illuminating device (12) is provided with a light source (33); a chassis (14) which stores the light source (33); a heat transfer section (24) which transfers heat generated by the light source (33); and a columnar member (50) for maintaining the shape of the chassis (14).  The columnar member (50) is composed of a hollow member arranged on the opposite side to the light source (33) in the chassis (14).  On the hollow member, opening sections (52a, 52b) which penetrate from the inside to the outside are formed.  The heat transfer section (24) is arranged on the chassis (14) at a position where the heat transfer section is superimposed on at least the light source (33), and the heat transfer section extends from the position where the heat transfer section is superimposed on the light source (33) to the columnar member (50).
