Title:
ORIENTATION TREATMENT
Document Type and Number:
Japanese Patent JPH0588180
Kind Code:
A
Abstract:
PURPOSE:To rub an oriented film uniformly over the entire area and to obtain uniform orientability by rubbing the oriented film surface in the state of covering the terminals of electrodes with the oriented film as well, then removing the oriented film on terminal arranging part. CONSTITUTION:The oriented film 3 consisting of a polyimide resin, etc., is formed on a substrate 1 formed with transparent electrodes 2 and the terminals 2a thereof from the top of the electrode forming region (display region) S to the top of the terminal arranging part. The oriented film 3 in such a case is formed at the width at which the electrode forming region S is completely covered and in the band-shaped pattern extending to the overall length of the substrate along the moving direction of a rubbing roller 4. Then the film surface of the oriented film 3 is rubbed by the rubbing roller 4. The oriented film 3 in the part on the side outer than the electrode forming region S, i.e., on the outer peripheral edge part of the substrate inclusive of the terminal arranging part is etched away to allow the oriented film 3 to remain only on the electrode forming region S and to expose the respective terminals 2a arranged in the terminal arranging part, by which the orientation treatment is completed.
