摘要： An organic electroluminescent element that uses a compound expressed by the following general formula emits dark blue light and exhibits little change in chromaticity during brightness modulation. (n1 is an integer from 0 to 8; the R1 [groups] are each independently a substituent substituted for a hydrogen atom of the pyrene skeleton; X is CRaRb (Ra and Rb are each independently a hydrogen atom or a substituent), O, S, or SiRdRe (Rd and Re are each independently a hydrogen atom or a substituent); and A1 to A4 represent each independently either N or CRf (Rf represents a hydrogen atom or a substituent, and two adjacent Rf [groups] may jointly form a saturated or unsaturated ring, but no more than two rings may be formed jointly by two or more of the Rf [groups]).)

摘要： The liquid crystal composition of the present invention contains a compound represented by the following Formula (1) and a liquid crystal. In Formula (1), at least one among R1 to R7 is a liquid crystalline substituent, and those among R1 to R7 that are not a liquid crystalline substituent each independently represent a hydrogen atom or a substituent. X and Y each independently represent an alkyl group, a halogen atom, an alkoxy group, or an alkylthio group. Z represents an alkyl group having 3 or more carbon atoms, an acyl group, or an aryl group. A represents an oxygen atom, a sulfur atom, or a nitrogen atom. n represents 0 or 1. The liquid crystal device, reflection display material, and light modulating material of the invention contain the liquid crystal composition.
