Abstract

In a method of treating a surface of a face panel for an image display including forming a film on the surface using coating materials, the film is formed of at least two layers including a first layer formed by a spray coating method and a second layer formed by a spin coating method to be superposed on the first layer. Thus, a face plate having antireflection/antistatic effects and providing high-resolution images can be obtained with high efficiency.

Claims

1. A method of treating a surface of a face panel for an image display, comprising:

forming a film on the surface using coating materials,

wherein the film comprises at least two layers including a first layer formed by a spray coating method and a second layer formed by a spin coating method to be superposed on the first layer.

2. The method of treating a surface of a face panel for an image display according to claim 1, wherein the coating material used for forming the first layer contains no binder component.

3. The method of treating a surface of a face panel for an image display according to claim 1, wherein the first layer has a mean surface roughness of less than 0.20 μ

m before the second layer is formed.

4. The method of treating a surface of a face panel for an image display according to claim 1, wherein the first layer has brittleness before the second layer is formed.

5. The method of treating a surface of a face panel for an image display according to claim 1, wherein the coating material used for forming the second layer is made of a material to react irreversibly.
