Patent ID: 8384850

Claim:
A liquid crystal display device, comprising: a liquid crystal display panel including a first substrate, a second substrate, and liquid crystal held between the first substrate and the second substrate; a backlight; a flexible printed wiring board connected to a part of the first substrate; a light-emitting diode substrate which has a plurality of light-emitting diodes mounted thereon; a connection substrate for connecting the light-emitting diode substrate and the flexible printed wiring board to each other; a first line for supplying a first power supply voltage to the plurality of light-emitting diodes; and a plurality of second lines for supplying a second power supply voltage to each of the plurality of light-emitting diodes, the plurality of second lines being equal in number to the plurality of light-emitting diodes, wherein: the first line and the plurality of second lines are formed on the light-emitting diode substrate and on the connection substrate; the plurality of second lines are arranged, on the connection substrate, in the same direction as a direction in which the plurality of light-emitting diodes mounted on the light-emitting diode substrate are arranged; the first line is formed outside the plurality of second lines, on the connection substrate; the plurality of second lines are formed without intersecting with one another, on the light-emitting diode substrate; and the first line is formed, on the light-emitting diode substrate, so that the first line extends along with a periphery of the light-emitting diode substrate from a connection part with respect to the connection substrate so as to come around to an opposite side of the connection part with respect to the connection substrate.
