Abstract

An approach is provided for manufacturing a LCD apparatus. A first substrate is formed by forming a transparent conductive layer on a first transparent insulating substrate and forming a transparent conductive electrode on the transparent conductive layer. A second substrate is formed by forming a thin-film transistor (TFT) on a second transparent insulating substrate and forming a pixel electrode. The first substrate is coupled to the second substrate using a sealing member.

Claims (22)

1. A method for manufacturing an LCD apparatus, the method comprising:

forming a first substrate;

forming a second substrate; and

coupling the first substrate and the second substrate together,

wherein the first substrate is formed by forming a transparent conductive layer, comprising a first material, on a first transparent insulating substrate and forming a transparent conductive electrode, comprising a second material different from the first material, on the transparent conductive layer, and

wherein the second substrate is formed by forming a thin-film transistor (TFT) on a second transparent insulating substrate and forming a pixel electrode.

2. The method of claim 1 , wherein the transparent conductive layer comprises a conductive polymer.

3. The method of claim 2 , wherein the transparent conductive layer is formed via a gravure-offset printing process.

4. The method of claim 3 , wherein the transparent conductive layer is formed by:

disposing a transparent conductive ink on a surface of a gravure roll;

transcribing the transparent conductive ink of the surface of the gravure roll on a first blanket roll;

transcribing the transparent conductive ink of the first blanket roll on a second blanket roll; and

transcribing the transparent conductive ink of the second blanket roll on the first transparent insulating substrate.

5. The method of claim 4 , wherein the gravure roll and the second blanket roll rotate in a first direction, and the first blanket roll rotates in a second direction different from the first direction.

6. The method of claim 4 , wherein the gravure roll includes a single pattern formed on the surface of the gravure roll, the single pattern having a first depth and a second depth deeper than the first depth.

7. The method of claim 3 , wherein the gravure-offset printing process utilizes a gravure roll and a deposition roll.

8. The method of claim 7 , wherein the gravure roll and the deposition roll each have a semi-cylindrical shape.

9. The method of claim 8 , further comprising a blanket roll disposed between the gravure roll and the deposition roll, the blanket roll having a cylindrical shape.

10. The method of claim 9 , wherein the gravure roll and the deposition roll rotate in a first direction, and the blanket roll rotates in a second direction different from the first direction.

11. The method of claim 8 , wherein the gravure roll and the deposition roll each have a cylindrical portion, a first groove, a second groove, and a protruding portion.

12. The method of claim 11 , wherein the cylindrical portion extends from a first edge of the first groove to a first edge of the second groove, and the protruding portion protrudes from a second edge of the first groove and a second edge of the second groove.

13. The method of claim 1 , wherein the first substrate and the second substrate are coupled together using a sealing member.
