Abstract

A display apparatus is disclosed. The display apparatus includes a transistor formed on a substrate; an interlayer insulator formed on the transistor; a pixel electrode formed on the interlayer insulator; a first partition located above a contact hole which penetrates the interlayer insulator; and a second partition which intersects with the first partition, or which is located on a straight line intersecting with the first partition, and which brings a width value of the pixel electrode to a predetermined value.

Claims (15)

1. A display apparatus, comprising:

a substrate;

a transistor formed on the substrate;

an interlayer insulator formed on the transistor;

a pixel electrode formed on the interlayer insulator;

a first partition located above a contact hole which penetrates the interlayer insulator; and

a second partition which intersects with the first partition, or which is located on a straight line intersecting with the first partition, and which brings a width value of the pixel electrode to a predetermined value.

2. The display apparatus as claimed in claim 1 , further comprising an auxiliary electrode formed across the interlayer insulator and the contact hole at a location between the contact hole and the first partition, wherein an end of the auxiliary electrode is located below the pixel electrode.

3. The display apparatus as claimed in claim 1 , wherein the contact hole is an electro-conductive post including an electro-conductive material.

4. The display apparatus as claimed in claim 3 , wherein the electro-conductive post protrudes from a surface of the interlayer insulator.

5. The display apparatus as claimed in claim 1 , wherein the first partition is a partition formed on the second partition.

6. The display apparatus as claimed in claim 1 , wherein one or both of the first partition and the second partition have a liquid-repellant property.

7. The display apparatus as claimed in claim 1 , wherein the second partition is a partition which is located such that it is generally orthogonal to the first partition, and such that it brings a width value of the pixel electrode to a predetermined value.

8. The display apparatus as claimed in claim 1 , further comprising an organic EL device which includes an organic light-emitting layer and an opposing electrode formed on the pixel electrode and neighboring the first partition.

9. The display apparatus as claimed in claim 1 , further comprising a display functional layer on the pixel electrode, and an opposing electrode on the display functional layer, wherein the display functional layer is one of an electrophoretic particle layer, an electrochromic layer, and a liquid crystal layer.
