The present invention relates to a radiation sensitive resin composition comprising [A] an alkali-soluble resin, [B] a 1,2-quinonediazide compound and [C] a radical trapping agent. The radiation sensitive resin composition can provide an interlayer insulating film which satisfies general requirements for an interlayer insulating film such as high light transmittance and has excellent heat-resistant dimensional stability, heat discoloration resistance and adhesion to a substrate along with the improvement of process efficiency for improving product yield at a high resolution and has excellent storage stability.

Radiation sensitive resin composition and method of forming an interlayer insulating film

A liquid crystal display device includes an alignment sustaining layer formed of a photopolymerized material on each of surfaces of a pair of alignment films which are closer to a liquid crystal layer. The alignment sustaining layer is configured to regulate a pretilt azimuth of a liquid crystal molecule of the liquid crystal layer during absence of an applied voltage. A nematic liquid crystal material of the liquid crystal layer comprise a liquid crystal compound having a terphenyl ring system as an indispensable component, and the liquid crystal layer further comprises part of a photopolymerizable compound. A content of the photopolymerizable compound relative to the nematic liquid crystal material is less than 0.015 mol %.

Liquid crystal display device

A liquid crystal display device of the present invention includes: a liquid crystal layer containing a nematic liquid crystal material; a pair of electrodes opposing each other via the liquid crystal layer; a pair of alignment films respectively provided between the pair of electrodes and the liquid crystal layer; and an alignment sustaining layer formed of a photopolymerized material on each of surfaces of the pair of alignment films which are closer to the liquid crystal layer, the alignment sustaining layer being configured to regulate a pretilt azimuth of a liquid crystal molecule of the liquid crystal layer during the absence of an applied voltage across the liquid crystal layer, wherein the pretilt azimuth of the liquid crystal molecule of the liquid crystal layer is regulated by the alignment sustaining layer during the absence of an applied voltage across the liquid crystal layer. The nematic liquid crystal material contains a liquid crystal compound having a terphenyl ring system as an indispensable component, and the liquid crystal layer further contains part of a photopolymerizable compound which is a source material of the photopolymerized material, a content of the photopolymerizable compound relative to the nematic liquid crystal material being less than 0.015 mol %.
