PROBLEM TO BE SOLVED: To provide a liquid crystal display device having an alignment layer hardly inducing a burn-in phenomenon of a displayed image.SOLUTION: The crystal display device includes: a first substrate and a second substrate, at least one of which is transparent; a liquid crystal layer disposed between the first substrate and the second substrate; a group of electrodes for applying an electric field to the liquid crystal layer, which is formed on at least one of the first substrate and the second substrate; a plurality of active elements connected to the group of electrodes; and an alignment layer disposed on at least one of the first substrate and the second substrate. In the device, the alignment layer contains a polyimide and a polyimide precursor formed by using a diamine and an acid anhydride, and the diamine contains a first diamine having at least an acidic group and a second diamine having at least one nitrogen atom-containing functional group other than two amino groups. |
