Abstract

The present invention relates to a ray sensitive resin composition, a curing film used for a display element, a forming method for the curing film used for the display element, and the display element. The present invention aims at providing a ray sensitive resin composition having a full resolution ratio even roasted at a low temperature, a curing film used for a display element having excellent heat resistance, reagent resistance, light-admitting quality, and solidification, and a display element having an excellent voltage holding ratio. The ray sensitive resin composition comprises: [A] a copolymer containing 0.1mole%-35mole% (a1) construction unit represented by the following formula (1); [B] a polymerizable compound having an ethylene unsaturated bond; and [C] a ray sensitive polymerization initiator.

Description

technical field [0001] The present invention relates to a radiation-sensitive composition, a cured film for a display element, a method for forming a cured film for a display element, and a display element. Background technique [0002] Radiation-sensitive resin compositions are widely used as materials for forming cured films for display elements such as interlayer insulating films, spacers, and protective films. As such a radiation-sensitive resin composition, for example, a composition containing a copolymer of an unsaturated carboxylic acid, an epoxy group-containing unsaturated compound, or the like is known (see JP-A-2001-354822). When such a composition is used to form, for example, a spacer for a display element, it is necessary to perform a firing process at a high temperature in order to increase the surface hardness of the spacer to a commercially required level. [0003] On the other hand, flexible displays such as e-paper are now popularized. Plastic substrate...
