Abstract

Provided is a liquid crystal display device including a frame for accommodating light emitting diode substrates, the frame including: a first surface opposed to the light emitting diode substrates; a second surface that erects from the first surface around the light emitting diode substrates; and a third surface on an opposite side to the first surface; a connector attached to each of the light emitting diode substrates; a circuit board disposed on the third surface of the frame; and at least one cable for electrically connecting the connector with the circuit board. The at least one cable extends from the connector in a direction approaching the circuit board on the first surface so as to detour around the light emitting diode substrates, passes through the frame from the first surface to the third surface, and is electrically connected to the circuit board on the third surface.

Claims (25)

1. A liquid crystal display device, comprising:

a liquid crystal display panel;

a plurality of light emitting diode substrates each having a plurality of light emitting diodes mounted thereon;

a frame for accommodating the plurality of light emitting diode substrates, the frame including:

a first surface opposed to the plurality of light emitting diode substrates;

a second surface that erects from the first surface around the plurality of light emitting diode substrates; and

a third surface on an opposite side to the first surface;

a connector attached to each of the plurality of light emitting diode substrates;

a circuit board disposed on the third surface of the frame; and

at least one cable for electrically connecting the connector with the circuit board,

wherein the at least one cable extends from the connector in a direction approaching the circuit board on the first surface so as to detour around the plurality of light emitting diode substrates, passes through the frame from the first surface to the third surface, and is electrically connected to the circuit board on the third surface.

2. The liquid crystal display device according to claim 1 , wherein:

the plurality of light emitting diode substrates are arranged so as to avoid an end portion of the first surface; and

the at least one cable is arranged so as to run on the end portion of the first surface.

3. The liquid crystal display device according to claim 2 , further comprising a reflection sheet that is disposed on the plurality of light emitting diode substrates and has a plurality of holes formed therein, each of the plurality of light emitting diodes being disposed inside each of the plurality of holes,

wherein the reflection sheet has a shape that extends so as to cover above the at least one cable and go over the second surface.

4. The liquid crystal display device according to claim 1 , wherein the plurality of light emitting diode substrates are arranged adjacent one another within the frame.

5. The liquid crystal display device according to claim 4 , wherein the plurality of light emitting diode substrates are arranged in a plurality of rows and a plurality of columns.

6. The liquid crystal display device according to claim 4 , wherein each of the plurality of light emitting diode substrates has a rectangular flat shape, and two of the plurality of light emitting diode substrates are arranged such that short sides thereof are opposed to each other.

7. The liquid crystal display device according to claim 4 , wherein each of the plurality of light emitting diode substrates has a rectangular flat shape, and the plurality of light emitting diode substrates are arranged such that long sides of adjacent ones are opposed to each other.

8. The liquid crystal display device according to claim 4 , wherein:

each of the plurality of light emitting diode substrates has a rectangular flat shape;

two of the plurality of light emitting diode substrates are arranged such that short sides thereof are opposed to each other; and

the plurality of light emitting diode substrates are arranged such that long sides of adjacent ones are opposed to each other.

9. The liquid crystal display device according to claim 4 , wherein the plurality of light emitting diode substrates lie in one plane, and the first surface of the frame lies in a plane which is substantially parallel to the one plane.
