Problems solved by technology

However, in the case of a photosensitive resin composition using an epoxy-based crosslinking agent, since the epoxy group that undergoes a crosslinking reaction has high reactivity, storage stability becomes a problem, and there are troubles such as reduced operability. It is difficult to balance the characteristics and operability of cured products

Abstract

To provide a photosensitive resin composition capable of being used for forming a spacer which has high hardness, little plastic deformation amount when it is compressed, heat resistance required as a permanent film, and chemical durability; and the spacer formed by using the same. The photosensitive resin composition for the display panel contains, which has the characteristics of (A) an alkali-soluble, carboxyl group-containing photosensitive resin, (B) a polymerizable compound having an ethylenic unsaturated bond, (C) a photopolymerization initiator, and (D) a compound having a oxazin ring.

Description

technical field [0001] The present invention relates to a photosensitive resin composition for display panels, a cured product thereof, and a spacer for display panels formed from the cured product. More specifically, it relates to a photosensitive resin composition excellent in storage stability and compressive strength, a cured product thereof, and a display panel-use material suitable as a material for forming a spacer for a display panel such as a liquid crystal panel or a touch panel. spacer. Background technique [0002] Conventionally, in a liquid crystal panel, spacer particles such as glass beads or plastic beads having a predetermined particle diameter have been used in order to maintain a constant distance between two substrates. However, these spacer particles are randomly scattered on the glass substrate. Therefore, when the above-mentioned spacers are present in the effective pixel portion, there will be an image of the spacers, and incident light will be scat...
