Abstract

Provided is a method for fabricating a liquid crystal panel, comprising: coating a thermal sensitive adhesive on an outer surface of a plastic substrate; attaching a glass substrate on the thermal sensitive adhesive; performing a liquid crystal cell process on an inner surface of the plastic substrate; and separating the glass substrate from the plastic substrate.

Claims (21)

1. A method for fabricating a liquid crystal panel, comprising:

coating a thermal sensitive adhesive on an outer surface of a plastic substrate;

attaching a glass substrate on the thermal sensitive adhesive;

performing a liquid crystal cell process on an inner surface of the plastic substrate; and

separating the glass substrate from the plastic substrate,

wherein separating the glass substrate is performed at a temperature where the thermal sensitive adhesive loses its adhering ability and is changed into a solid state.

2. The method according to claim 1 , wherein the thermal sensitive adhesive is coated at a room temperature where the thermal sensitive adhesive is in a non-solid state.

3. The method according to claim 1 , wherein the thermal sensitive adhesive has an acryl resin as a base component thereof.

4. The method according to claim 1 , wherein the temperature is set at a range of about 0° C. to 10° C.

5. A method for fabricating a liquid crystal panel, comprising:

coating a thermal sensitive adhesive on a first surface of a first plastic substrate and a first surface of a second plastic substrate;

attaching a glass substrate on the thermal sensitive adhesive;

forming a TFT array on a second surface of the first plastic substrate and a second surface of the second plastic substrate;

attaching the first and second substrates such that the second surface of the first plastic substrate faces the second surface of the second plastic substrate; and

separating the thermal sensitive adhesive and the glass substrate attached on the thermal sensitive adhesive from the first and second plastic substrates,

wherein separating the glass substrate is performed at a temperature where the thermal sensitive adhesive loses its adhering ability and is changed into a solid state.

6. The method according to claim 5 , further comprising forming a liquid crystal layer between the second surface of the first plastic substrate and the second surface of the second plastic substrate after the attaching is performed.

7. The method according to claim 5 , wherein the thermal sensitive adhesive is coated at a room temperature where the thermal sensitive adhesive is in a non-solid state.

8. The method according to claim 5 , wherein the thermal sensitive adhesive has acryl resin as a base component thereof.

9. The method according to claim 8 , wherein the thermal sensitive adhesive contains 90% or more hexadecyl acrylate or octadecryl acrylate and additives of MA (methaacrylate) and MAA (methyl methaacrylate).

10. The method according to claim 5 , wherein the temperature is set at a range of 0° C. to 10° C.
