<p>Provided are a radiation sensitive resin composition, a protrusion and a spacer formed from the composition which have improved various capabilities such as pattern form, spacer strength, rubbing resistance, close adhesion with transparent substrate, and heat resistance, and a liquid crystal display device comprising them which exhibits high reliability for a long time. The radiation sensitive resin composition comprises [A] copolymer of ethylenically unsaturated carboxylic acid and(or) ethylenically unsaturated carboxylic anhydride(a1) and ethylenically unsaturated compound other than (a1), [B] polymerizable compound having ethylenically unsaturated bond, and [C] photopolymerization initiator. The amount of the photopolymerization initiator is 0.1-5 parts by weight in respect to 100 parts by weight of the ingredient [B]. The method for simultaneously forming the protrusion and spacer of the liquid crystal display device comprises the steps of (i) forming a coating of the radiation sensitive composition on substrate, (ii) irradiating at least a part of the coating under low oxygen condition, (iii) developing the substrate, and (iv) heating the substrate.</p> |
