摘要： There is provided a composition for forming an EUV resist overlayer film that is used in an EUV lithography process, that does not intermix with the EUV resist, that blocks unfavorable exposure light for EUV exposure, for example, UV light and DUV light and selectively transmits EUV light alone, and that can be developed with a developer after exposure. A composition for forming an EUV resist overlayer film used in an EUV lithography process including a resin containing a naphthalene ring in a main chain or in a side chain and a solvent, in which the resin may include a hydroxy group, a carboxy group, a sulfo group, or a monovalent organic group having at least one of these groups as a hydrophilic group.

摘要： A liquid crystal display device, which includes a first substrate and a second substrate disposed to face each other with a liquid crystal sandwiched therebetween. The first substrate is an electrode-provided substrate having a first electrode and a plurality of second electrodes overlaid on the first electrode via an insulating film, formed on a pixel region on a surface on the liquid crystal side, where one of the first electrode and the second electrodes is a pixel electrode and the other is a counter electrode, having a first liquid crystal alignment film formed on the surface on the liquid crystal side of the first substrate covered with the second electrodes. The second substrate is a substrate having a second liquid crystal alignment film formed on a surface on the liquid crystal side, the second liquid crystal alignment film containing a photosensitive side chain type polymer which develops liquid crystallinity.
