PROBLEM TO BE SOLVED: To provide a photosensitive resin which has high photo-setting properties, with which a liquid crystal spacer excellent in characteristics such as mechanical strength can be formed and to which alkali development properties can be imparted without sacrificing the photo-setting properties, for the purpose of providing a columnar spacer by which the interval between surface flat bodies of a liquid crystal cell can be regularly controlled and maintained for a long time, in a large size liquid crystal display device, and to provide a resin composition. SOLUTION: The photosensitive resin for forming the liquid crystal spacer for regularly maintaining the interval of the surface flat bodies, in the liquid crystal cell wherein a liquid crystal composition is encapsulated between the two surface flat bodies separated at a regular interval from each other, can be characteristically obtained in such a manner that an epoxy resin containing epoxy resin having two epoxy groups in one molecule as the essential component is reacted with an unsaturated monobasic acid, successively with a polybasic acid anhydride and resultingly formed carboxyl groups sre reacted with a compound having two or more functional groups which can be reacted with the carboxyl groups in one molecule. |
