Abstract
The invention provided a radiation sensitive resin composition for spacers capable of suppressing stain of a photomask, etc., due to sublimation of a radiation sensitive polymerization initiator component, producing no in-liquid foreign substance, having high sensitivity and high resolution, and capable of forming spacers excellent in the shape of a cross section, compressive strength, rubbing resistance and adhesiveness to a transparent substrate. The radiation sensitive resin composition for forming spacers contains (A) a copolymer of an unsaturated carboxylic acid (anhydride), an epoxy-containing unsaturated compound and another unsaturated compound, (B) a polymerizable unsaturated compound, and (C) a radiation sensitive polymerization initiator containing a compound represented by formula (1) as an essential component, wherein R<SP>1</SP>denotes alkyl; R<SP>2</SP>and R<SP>3</SP>each denotes H, alkyl or benzyl; R<SP>4</SP>, R<SP>5</SP>, R<SP>7</SP>and R<SP>8</SP>each denotes H, halogen, alkyl or alkoxyl; and R<SP>6</SP>denotes halogen, alkyl, alkoxyl or the like.
Description
Technical field
The present invention relates to partition forms with radiation sensitive resin composition, partition and forming method thereof and liquid crystal display cells, more particularly, partition that the present invention relates to be fit to be used as the radiation sensitive resin composition of the partition that uses in the display panels such as forming display panels or contact type panel, forms by said composition and forming method thereof and liquid crystal display cells with this partition.
Background technology
In the past, in order to make two intervals (cell gap) between the transparency carrier keep certain, in liquid crystal display cells, use partition particles such as glass microballoon with regulation particle diameter or plastics microballon, but, because these partition particles are to be dispersed in randomly on the transparency carrier such as glass substrate, thereby form when having the partition particle in the zone when pixel, the phenomenon that the partition particle is written into will take place, perhaps incident light generation scattering makes the problems such as contrast reduction of liquid crystal display cells.
In order to address these problems, people adopt photoetching to form the method for partition.This method is, on substrate, form the tunicle of radiation sensitive resin composition, mask by regulation carries out ultraviolet exposure, develop then, form the partition of point-like or striated, because only the regulation position beyond pixel forms the zone forms partition, thereby has solved above-mentioned problem basically.
, form in the process of partition, for example adopt photoetching in color filter etc., to form the occasion of partition on the employed transparency carrier, often use the proximity printing machine in reality.When carrying out this proximity printing, more satisfactory method is, at the used mask of exposure and formed and expose after between the substrate of radiation sensitive resin composition tunicle certain interval being set, so just can expose according to the pattern of mask.Yet, owing in this interval, be full of air or nitrogen, make the light of the peristome (hyalomere) that sees through mask in this gap, spread and broaden, thereby the what is called problem wideer etc. of exposing occur than the design size of mask pattern.
In order to address this problem; the applicant finds and points out in patent documentation 1; by using 1; 2-octadione-1-[4-(thiophenyl) phenyl]-2-(O-benzoyl oximes) is as the radiation-sensitive polymerization initiator of radiation sensitive resin composition; even carry out proximity printing; also can verily reproduce the design size of mask pattern, in addition, can form all excellent display panel partition such as intensity and thermotolerance.
