RADIATION SENSITIVE RESIN COMPOSITION FOR FORMING PROJECTION OR SPACER FOR VERTICALLY ALIGNED LCD COMPRISING ALKALI-SOLUBLE RESIN, 1,2-QUINONEDIAZIDE COMPOUND AND SPECIFIC MELAMINE COMPOUND AND/OR AT LEAST TWO EPOXY GROUPS-CONTAINING COMPOUND, PROJECTION OR SPACER FOR VERTICALLY ALIGNED LCD, VERTICALLY ALIGNED LCD PROVIDED WITH THE PROJECTION OR SPACER, AND FORMATION METHOD OF THE PROJECTION OR SPACER USING THE COMPOSITION

摘要

PURPOSE: Provided are a radiation sensitive resin composition containing a specific melamine compound, a projection or spacer for a vertically aligned LCD formed from the composition which is excellent in resolution, residual film rate, pattern profile, heat resistance, solvent resistance and transparency, a vertically aligned LCD provided with the projection or spacer which is excellent in alignment and voltage holding rate, and a method for forming the projection or spacer by using the composition. CONSTITUTION: The radiation sensitive resin composition comprises an alkali-soluble resin; a 1,2-quinonediazide compound; and a compound represented by the formula 1 and/or a compound which has at least two epoxy groups in molecule, wherein R1 to R6 are independently H or -CH2OR; and R is H or a C1-C6 linear or branched alkyl group. Preferably the alkali-soluble resin is a novolac resin.
