The present invention is to provide a laminate that includes a polarizer and a photo alignment film and is excellent in the moisture-heat resistance of the polarizer, a method of producing a laminate, a polarizing plate, a liquid crystal display device, and an organic EL display device including the laminate. The laminate of the present invention includes a polarizer, and a photo alignment film that is adjacently arranged on the polarizer, the photo alignment film is a layer formed by bringing a composition for forming a photo alignment film into direct contact with a surface of the polarizer, and the composition for forming a photo alignment film contains Compound A having a photo-aligned group and Compound B having a crosslinking group, or Compound C having a photo-aligned group and a crosslinking group.
本发明旨在提供一种包括偏光片和光对准膜且偏光片的耐湿热性优异的层压板、一种生产层压板的方法、一种偏光板、一种液晶显示装置和一种包括该层压板的有机EL显示装置。本发明的层压板包括偏光片和相邻排列在偏光片上的光配准膜,光配准膜是通过使形成光配准膜的组合物与偏光片表面直接接触而形成的层,形成光配准膜的组合物包含具有光配准基团的化合物A和具有交联基团的化合物B,或具有光配准基团和交联基团的化合物C。
