Abstract

Provided is an edge light type illuminating device, in which an adverse effect of noise and the amount of electric wires are decreased by reducing the length of power supply wires arranged to supply electric power to light sources. An illuminating device ( 20 ) includes a chassis plate ( 22 ) having a square shape in a plan view, edge light type light sources ( 28 ) disposed along at least one side face of the plate and another side face perpendicular to the one side face, power supply means ( 30 ) arranged to supply electric power to the light sources, and a power supply wire arranged to electrically connect the light sources and the means, wherein at least a portion of the power supply wire includes bridging wires ( 33 ac, 33 bd ) arranged to connect the light sources perpendicular to each other.

First claim

The invention claimed is:

1. A liquid crystal display device comprising:
a liquid crystal display panel; and
an illuminating device disposed on a back side face of the liquid crystal display panel, and arranged to project light onto the liquid crystal display panel, the illuminating device comprising:
a chassis plate having a square shape when seen in a plan view;
edge light type light sources that are disposed along at least one side face of the chassis plate and another sid…
