Abstract

A display includes: a display panel; and a flexible circuit board connected to the display panel, and including power source lines for supplying driving current to the display panel, a signal line for transmitting a control signal to the display panel, and an integrated circuit element, in which the flexible circuit board includes a metal pattern connected to the power source lines, and the metal pattern is in contact with an outer surface of the integrated circuit element directly or via a thermal conductor.

Claims

1. A display comprising:

a display panel; and

a circuit board connected to a periphery of the display panel, and including a power source line for supplying driving current to the display panel, a signal line for transmitting a control signal to the display panel, and an integrated circuit element electrically connected to the signal line,

wherein the circuit board includes a metal pattern connected to the power source line, and

the metal pattern is in contact with an outer surface of the integrated circuit element directly or via a thermal conductor.

2. The display according to claim 1,

wherein the metal pattern is a part of the power source line.

3. The display according to claim 2,

wherein the metal pattern and the power source line are made of the same material.

4. The display according to claim 1,

wherein the thermal conductor has a thermal conductivity higher than a thermal conductivity of the metal pattern.

5. The display according to claim 1,

wherein the display panel includes:

a pixel area in which pixels are arrayed in a matrix; and

a line area provided to a periphery of the pixel area,

in the line area, an electrode pattern connected to an electrode in the pixel area is formed, and

the power source line is connected to the electrode pattern.

6. The display according to claim 5,

wherein the electrode pattern is formed in a shape of a picture frame.
