Liquid crystal display device
View Patent ↗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. 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.
1. 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.
