Title:
POLYMERIZABLE LIQUID CRYSTAL MIXED COMPOSITION, RETARDATION PLATE, ELLIPTICALLY POLARIZING PLATE AND ORGANIC EL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/014949
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a polymerizable liquid crystal mixed composition which has excellent solubility in a solvent and excellent film forming properties, and which ideally is favorable for the production of retardation plates which exhibit reverse wavelength dispersion properties and which have excellent optical characteristics. This polymerizable liquid crystal mixed composition contains at least 3 types of polymerizable liquid crystal compounds which have different molecular structures and are represented by formula (I). Said polymerizable liquid crystal compounds include polymerizable liquid crystal compounds in which Ea and Eb in formula (I) are identical to each other; defining the polymerizable liquid crystal compound (I-1), represented by formula (I-1), as the polymerizable liquid crystal compound in which the carbon number of alkanediyl groups represented by Ea and Eb is the lowest, the polymerizable liquid crystal mixed composition contains said polymerizable liquid crystal compound (I-1), a polymerizable liquid crystal compound (I-2) which is defined on the basis of the structure of said polymerizable liquid crystal compound (I-1) and is represented by at least one formula (I-2), and the polymerizable liquid crystal compound (I-3) which is defined on the basis of the structure of said polymerizable liquid crystal compound (I-1) and is represented by at least one formula (I-3).
