Abstract

A display device includes a first substrate provided with a pixel circuit in a display region, a second substrate provided facing the first substrate, a dam agent bonding the first substrate and the second substrate and sealing the display region, and a moisture detection part provided between a first region provided with the dam agent and the display region.

Claims (16)

1. A display device comprising:

a first substrate provided with a pixel circuit in a display region;

a second substrate provided facing the first substrate;

a dam agent bonding the first substrate and the second substrate and sealing the display region; and

a moisture detection part provided between a first region provided with the dam agent and the display region,

wherein the moisture detection part comprises a mixture of a coloring or light emitting material to a material of the dam agent, and the coloring or light emitting material is coloring or light emitting in response to moisture.

2. The display device according to claim 1 , wherein the moisture detection part including a material of electrical resistance changes in response to moisture.

3. The display device according to claim 1 , wherein a second region provided with the dam agent is provided between the moisture detection part and the display region.

4. The display device according to claim 3 , wherein the moisture detection part including a material of electrical resistance changes in response to moisture.

5. The display device according to claim 3 , wherein the moisture detection part including a first moisture detection surface contacting the first substrate and a second moisture detection surface contacting the second substrate, and a component for dividing the first moisture detection surface and the second moisture detection surface is provided between the first moisture detection surface and the second moisture detection surface.

6. The display device according to claim 5 , wherein the component includes a property for reflecting light.

7. The display device according to claim 1 , wherein the moisture detection part is included a coloring or light emitting material, and the coloring or light emitting material is coloring or light emitting in response to moisture.

8. The display device according to claim 1 , wherein the moisture detection part contacting the first substrate and the second substrate.

9. The display device according to claim 1 , wherein at least one of the first substrate or the second substrate is transparent in the moisture detection part.

10. The display device according to claim 1 wherein the first substrate and the second substrate comprises a resin.

11. The display device according to claim 1 , wherein the pixel circuit is provided with an organic EL device in a pixel.
