The present invention addresses the problem of providing a polarizer having a high degree of orientation and an image display device having the polarizer. This polarizer is formed from a polarizer-forming composition that contains a liquid-crystal compound, a first dichroic substance, and a second dichroic substance, wherein the polarizer has an array structure formed from the first dichroic substance, and an array structure formed from the second dichroic substance. La présente invention aborde le problème de la fourniture d'un polariseur ayant un degré élevé d'orientation et un dispositif d'affichage d'image ayant le polariseur. Ce polariseur est formé à partir d'une composition de formation de polariseur qui contient un composé à cristaux liquides, une première substance dichroïque et une seconde substance dichroïque, le polariseur ayant une structure de réseau formée à partir de la première substance dichroïque, et une structure de réseau formée à partir de la seconde substance dichroïque. 本発明は、配向度の高い偏光子および上記偏光子を有する画像表示装置を提供することを課題とする。本発明の偏光子は、液晶性化合物と、第１の二色性物質と、第２の二色性物質と、を含有する偏光子形成用組成物から形成される偏光子であって、第１の二色性物質から形成される配列構造と、第２の二色性物質から形成される配列構造とを有する、偏光子である。
