Liquid crystal display device

A liquid crystal display device comprising:

• a TFT substrate having a first alignment film;
• a counter substrate having a second alignment film and a pair of light shielding regions, the counter substrate being bonded to the TFT substrate by a seal material;
• and
• liquid crystals sealed inside the substrates and the seal material;
• wherein the counter substrate has a UV-light absorption layer formed between the pair of light shielding regions,
• the second alignment film is optically aligned by UV-light,
• the second alignment film is formed between the UV-light absorption layer and the liquid crystals,
• the seal material is a UV-light curable resin, and
• the transmittance of the UV-light absorption layer to UV-light at a wavelength of 300 nm is lower than that to UV-light at a wavelength of 340 nm.
