Description

technical field

[0001] The present invention relates to a curable resin composition containing a specific resin, a spacer, an interlayer insulating film, a microlens, or a method for forming a cured film as a protective film using the same, and a cured film. Background technique

[0002] <Prior Art Regarding Spacers>

[0003] In liquid crystal display elements, in order to maintain a constant distance between two transparent substrates, spacer particles such as glass beads and plastic beads having a predetermined particle size have been used. These spacer particles are randomly dispersed on transparent substrates such as glass substrates. Therefore, if the spacer particles are present in the image forming region, there is a problem that the reflection phenomenon of the spacer particles occurs, or the incident light scatters, and the contrast of the liquid crystal display element decreases.

[0004] Therefore, in order to solve these problems, a method of forming space...
