Problems solved by technology

Therefore, it cannot be said that the effect of removing attached substances is sufficient
[0006] In addition, as in Japanese Patent Application Laid-Open No. H6-96673, in the method of covering the top of the partition wall with a resist film, when trying to form a uniform resist film, the height of the partition wall is limited
In addition, a resist stripping liquid such as acetone is used in stripping using a resist film, therefore, the resin component of the functional layer formed between the partition walls is dissolved, and problems due to pattern stripping and film reduction may occur. Rough surface and uneven film thickness

example 1

[0035] based on Figures 1A to 1H The manufacturing method of the display substrate exemplified in the following steps is used to manufacture the display substrate.

[0036] (Step 1: Forming the Light Shielding Layer 2)

[0037] Black paste (NP-7811M1 manufactured by NORITAKE CO., LIMITED) was printed on the entire surface of the cleaned glass substrate 1 . The substrate 1 was dried at 150°C and then dried at 1000mJ / cm 2 It was exposed, developed, and baked at 580° C. to form a light shielding layer 2 having a thickness of 5 μm and openings with a horizontal pitch of 210 μm, a vertical pitch of 630 μm, and an opening size of 150×200 μm.

[0038] (Step 2: Forming Partition 3)

[0039] An insulating paste obtained by adding alumina having an average particle diameter of about 5 μm to borosilicate glass was deposited on the center line between the 210 μm pitches of the pixels of the light shielding layer 2 by a slit coater . The substrate was dried at 95°C and then heated at...

Abstract

The invention relates to a manufacturing method of a display substrate and a manufacturing method of an image display apparatus. The present invention provides a manufacturing method of a display substrate that can easily remove a substance adhering to the top of partition walls with high precision. On a substrate, partition walls for dividing a surface of the substrate into a plurality of regions are formed, and a color filter layer and a light emitting layer are formed in the regions. Then, a water solvable polymer layer is deposited at the top of the partition walls, and a planarized layer is formed on the light emitting layer. Then, the water solvable polymer layer formed on the top of the partition walls is removed by water rinsing to remove a substance adhering to the top of the partition walls.

Description

technical field [0001] The present invention relates to a method of manufacturing a display substrate having functional layers such as a light-emitting layer for emitting light in response to electron bombardment in a plurality of regions divided by partition walls, and a method of manufacturing an image display device using the same. Background technique [0002] Plasma displays (PDPs) and field emission displays (FEDs), which are known as flat panel displays, have partition walls in their internal structures, and functional layers are formed in a plurality of regions divided by the partition walls. For example, in a PDP, electrode layers, insulating layers, and phosphor layers are formed in regions divided by partition walls, and in FEDs, pigment layers, phosphor layers, and planarization layers are formed in regions divided by partition walls middle. Generally, when these functional layers are formed, a method of dropping a paste including constituent materials of the fu...
