Abstract

A lighting device 12 according to the present invention includes: a light source 18; a power supply board 20 configured to supply drive power to the light source 18; and a connector 21 that electrically connects the light source 18 to the power supply board 20. The power supply board 20 includes a connecting portion 20c connected with the connector 21 so as to be electrically connected to the light source 18 via the connector 21. The connecting portion 20c includes a rounded corner 20f.

Description

technical field [0001] The present invention relates to an illuminating device, a display device and a television receiving device. Background technique [0002] For example, a liquid crystal panel used in a liquid crystal display device such as a liquid crystal television does not emit light by itself, and therefore requires a backlight device as an additional lighting device. The backlight device is arranged on the back side of the liquid crystal panel (the side opposite to the display surface), and has: a base with an opening on the liquid crystal panel side; a plurality of lamps (for example, cold cathode tubes) accommodated in the base; and can Inverter board that supplies power to each lamp. [0003] As an example of a structure for electrically connecting an inverter board and a lamp, what is described in the following patent document 1 is known. The content is that the lamp is arranged inside the front side of the base, the inverter board is arranged outside the ba...
