Abstract

The present invention provides a display device and a manufacturing method thereof with which driver cracks caused by a fall or the like can be suppressed. The display device according to the present invention includes: a display panel; a driver for driving the display panel; a substrate disposed on a display surface side of the display panel; and an adhesive layer for adhering the display panel and the substrate to each other. The driver is provided on an end portion of the display panel between the display panel and the substrate, and a resin member for absorbing an impact is provided between the driver and the substrate.

Claims

1. A display device comprising:

a display panel;

a driver for driving the display panel;

a substrate disposed on a display surface side of the display panel; and

an adhesive layer for adhering the display panel and the substrate to each other,

wherein the driver is provided between an end portion of the display panel and the substrate, and

a resin member for absorbing an impact is provided between the driver and the substrate.

2. The display device according to claim 1,

wherein at least one through hole is formed in the substrate in a position opposing the end portion of the display panel on which the driver is provided.

3. The display device according to claim 1,

wherein the resin member covers all surfaces of the driver.

4. The display device according to claim 1,

wherein the resin member has a modulus of elasticity of 1×

10⁶ Pa or less.

5. The display device according to claim 1,

wherein the substrate is a cover substrate.

6. The display device according to claim 1,

wherein the display panel is a liquid crystal display panel or an organic electroluminescent display panel.

7. A manufacturing method for the display device according to claim 1,

wherein the manufacturing method comprises:

a through hole forming step of forming the through hole in the substrate in a position facing the end portion of the display panel on which the driver is provided;

a resin injecting step of injecting a resin through the through hole to cover at least a surface of the driver that opposes the substrate; and

a resin member forming step of forming the resin member by hardening the resin.

8. The manufacturing method for a display device according to claim 7,

wherein a thermosetting resin is used as the resin, and

in the resin member forming step, the resin is hardened by applying heat thereto.

9. The manufacturing method for a display device according to claim 7,

wherein the resin has a viscosity of 1 to 4 Pa·

s and a post-hardening modulus of elasticity of 1×

10⁶ Pa or less.
