Polarizer and liquid crystal display

A liquid crystal display, comprising:

• a pair of substrates at least one of which is transparent;
• a liquid crystal layer placed between the pair of substrates;
• an electrode group for applying an electric field to the liquid crystal layer, the electrode group being formed on at least one substrate of the pair of substrates;
• multiple active elements connected to the electrode group;
• an alignment control film placed on at least one substrate of the pair of substrates;
• and
• a polarizer provided on at least one surface of the alignment control film, the polarizer being obtained by cross-linking molecules of a dichroism pigment with a crosslinkable monomer and aligning the molecules of the dichroism pigment.

A reflective type liquid crystal display, comprising:

• a pair of substrates at least one of which is transparent;
• a liquid crystal layer placed between the pair of substrates;
• an electrode group for applying an electric field to the liquid crystal layer, the electrode group being formed on at least one substrate of the pair of substrates;
• multiple active elements connected to the electrode group;
• and
• a reflecting plate formed on the transparent substrate,
• wherein an alignment control film is formed on the reflecting plate so that a built-in polarization plate composed of molecules of a dichroism pigment aligned by the alignment control film is formed.
