Abstract

There are provided a display in which a sealing section is prevented from being spread and the sealing section is allowed to be provided in a desired region, and an electronic unit including the display. The display includes: a substrate including a sealing region and a step section, the sealing region surrounding a display region, and the step section surrounding the sealing region from outside; a display layer provided in the display region; and a sealing section provided in the sealing region.

First claim

What is claimed is:

1. A display, comprising:
a substrate that includes a display region, a sealing region and a step section,
wherein the sealing region surrounds the display region, and wherein the step section surrounds the sealing region from outside;
a display layer in the display region; and
a sealing section on the substrate in the sealing region,
wherein the step section includes a protruded wall that protrudes from a surface, of the substrate, on which the display layer is present, and
wherein a chemical composition of the protruded wall and a chemical composition of the surface of the substrate is same.

2. The display according to claim 1 ,
wherein the step section further includes a groove, and
wherein the groove is in the substrate.

3. The display according to claim 1 , wherein
the sealing region is subjected to treatment that improves wettability, and
the step section is subjected to water-repellent treatment.

4. The display according to claim 3 , wherein the sealing region is subjected to plasma treatment.

5. The display according to claim 3 , wherein the step section is subjected to silica-based surface treatment.

6. The display according to claim 1 ,
wherein the step section includes a plurality of grooves and a plurality of protruded walls, and
wherein the plurality of grooves are in the substrate, and the plurality of protruded walls protrude from the surface of the substrate.

7. An electronic unit, comprising:
a display, wherein the display comprises:
a substrate that includes a display region, a sealing region and a step section, wherein the sealing region surrounds the display region, and wherein the step section surrounds the sealing region from outside;
a display layer in the display region; and
a sealing section on the substrate in the sealing region,
wherein the step section includes a protruded wall that protrudes from a surface, of the substrate, on which the display layer is present, and
wherein a chemical composition of the protruded wall and a chemical composition of the surface of the substrate is same.
