Liquid crystal display using polymer stability alignment process with sealant pre-curing process

Abstract

A liquid crystal display (LCD) includes a bottom substrate having a top surface; a sealant located on the top surface of the bottom substrate, wherein the sealant has a pre-curing temperature; a liquid crystal mixture including a liquid crystal material and at least one reactive monomer located on the top surface of the bottom substrate and surrounded by the sealant, the at least one reactive monomer having a melting point higher than 120° C., wherein the melting point of the reactive monomer is higher than the pre-curing temperature of the sealant; at least one polymer layer polymerized from the reactive monomer, located between the bottom substrate and the liquid crystal material; and a top substrate covering the sealant and the bottom substrate to seal the liquid crystal mixture and the at least one polymer layer.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This is a continuation application of patent application Ser. No. 12 / 104,453 filed on Apr. 17, 2008, now allowed. The prior application Ser. No. 12 / 104,453 claims the benefit of Taiwan Patent Application No. 096139903 filed on Oct. 24, 2007, the disclosures of which are incorporated herein by reference in their entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a method for manufacturing a liquid crystal display, and more particularly, to a method for manufacturing a liquid crystal display comprising a liquid crystal mixture having a high melting point. 2. Description of the Prior Art[0004]With progression of large-sized liquid crystal displays (LCDs), a requirement for wider viewing angle is confronted. Therefore the multi-domain vertical alignment (MVA) LCD, which possesses advantages such as wider viewing angle and shorter response time, has become a mainstream of the large-sized L...

AI Technical Summary

Benefits of technology

This approach prevents the formation of mura in LCDs by ensuring the reactive monomer's stability throughout the manufacturing process, maintaining the composition and alignment of liquid crystal molecules, and enhancing the overall quality of the display.

Problems solved by technology

Therefore processes such as thin film deposition, photolithography process, and etching process are needed to form the protrusion, and thus complexity and cost of the fabrication are increased.

More serious, the protrusion shades light, reduces aperture ratio of the pixel, and reduces brightness of the LCD.

Therefore, during the following polymer stability alignment process, the polymerization and the phase separation of the reactive monomer cannot be effectively caused to make the liquid crystal molecules have pre-tilt angle.
