Problems solved by technology

However, the "black" nature of the resin-type black matrix composition is accompanied by high light-shielding properties. As a result, during the lithography process, the part of the composition closer to the substrate (the farther away from the light source) receives lower light, and the resin in this part has a greater impact on the substrate. The adhesion of the resin is often reduced due to incomplete cross-linking; therefore, it is necessary to develop a resin with high photosensitivity, high adhesion and excellent developability at the same time

Embodiment Construction

[0027] Herein, if it is not specified whether a certain group is substituted, the group may represent a substituted or unsubstituted group. For example, "alkyl" can mean substituted or unsubstituted alkyl. In addition, a certain group is marked with "C X "When described, it means that the main chain of the group has X carbon atoms.

[0028] Herein, the compound structure is sometimes represented by a skeleton formula. This notation can omit carbon atoms, hydrogen atoms, and carbon-hydrogen bonds. Of course, if an atom or an atomic group is clearly drawn in a structural formula, the drawn one shall prevail.

[0029] In this specification, the range expressed by "one numerical value to another numerical value" is a general expression which avoids enumerating all numerical values ​​within the range in the specification. Therefore, the description of a specific numerical range is intended to cover any numerical value in the numerical range and the smaller numerical range defin...

Abstract

The present invention provides a multi-acrylate compound, including multiple acrylate groups and groups represented by formula 1 or formula 2, wherein n is 0, 1 or 2, R1 is Cp alkylene-X1-Cq alkylene Alkyl, wherein p is an integer of 1 to 10, and q is an integer of 1 to 10; X1 is ‑CH2‑, ‑O‑ or ‑S‑; R2 is independently C1 to C4 alkyl; R3 is independently C1~C10 alkyl; and R4 is a divalent linking group.

Description

technical field [0001] The present invention relates to a polyacrylate-based compound (acrylic compound), and in particular to a polyacrylate-based compound having a carboxylic acid group (-COOH) and a silane (silane) group, and an acrylic compound comprising the polyacrylic compound Photosensitive resin composition of ester compound. Background technique [0002] Liquid crystal display (LCD) is a device that uses the photoelectric properties of liquid crystal materials to present image information. It has been widely used in personal computers, monitors, televisions, mobile phones, car navigation systems or personal digital assistances. , PDA) and other display fields. Generally, a liquid crystal display includes a pair of substrates and a liquid crystal material interposed therebetween. By applying an electric field to the liquid crystal material, it is determined whether light can pass through the liquid crystal material, thereby displaying grayscale images with differe...
