Benefits of technology

The patent text describes a photoresist composition used in the manufacturing process of a polarizer and display substrate. The composition has high resistance to a dry-etching process using plasma gas, which improves the reliability of the imprinting or nanoimprinting process. The composition also has a controlled viscosity without using an extra solvent, which eliminates the need for a pre-baking process to dry the solvent. This improves manufacturing efficiency.

Problems solved by technology

The polarizer absorbs light irradiated from the backlight assembly, so that the polarizer undesirably has a low level of efficiency and heat-resistance, and is easily deteriorated by an ultraviolet light.
However, a photoresist pattern formed by a conventional photoresist composition which is used in the nanoimprinting method is easily separated from a metal layer during a dry-etching process using a plasma gas, so that the efficiency and the reliability of the polarizer formed by the nanoimprinting method are reduced.

Embodiment Construction

[0033]It will be understood that when an element or layer is referred to as being “on” or “connected to” another element or layer, the element or layer can be directly on or connected to another element or layer or intervening elements or layers. In contrast, when an element is referred to as being “directly on” or “directly connected to” another element or layer, there are no intervening elements or layers present. As used herein, connected may refer to elements being physically and / or electrically connected to each other. Like numbers refer to like elements throughout. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0034]It will be understood that, although the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms are only used to dis...

Abstract

A photoresist composition includes about 65% by weight to about 80% by weight of a mono-functional monomer, about 5% by weight to about 20% by weight of a di-functional monomer, about 1% by weight to about 10% by weight of a multi-functional monomer including three or more functional groups, about 1% by weight to about 5% by weight of a photoinitiator, and less than about 1% by weight of a surfactant, each based on a total weight of the photoresist composition.

Description

[0001]This application claims priority to Korean Patent Application No. 10-2012-0039496, filed on Apr. 17, 2012, and all the benefits accruing therefrom under 35 U.S.C. §119, the contents of which are herein incorporated by reference in its entirety.BACKGROUND[0002]1. Field[0003]Exemplary embodiments relate to a photoresist composition, a method of manufacturing a polarizer and a method of manufacturing a display substrate using the photoresist composition. More particularly, exemplary embodiments relate to a photoresist composition that may be used in a nanoimprinting process for manufacturing a polarizer, a method of manufacturing a polarizer and a method of a display substrate using the photoresist composition.[0004]2. Description of the Related Art[0005]Generally, a liquid crystal display device is thinner and lighter than a cathode ray tube (“CRT”) display device, such that the liquid crystal display is widely used. However, the liquid crystal display device uses a liquid cryst...
