Liquid crystal display device

A liquid crystal display device including a first substrate, a liquid crystal layer, a second substrate, a retardation layer, and a polarizer in this order from a back face side, the liquid crystal display device comprising:

• a plurality of pixels arrayed in a matrix shape,
• wherein the first substrate includes a reflective layer that reflects light, a first electrode and a second electrode that are configured to generate a transverse electrical field in the liquid crystal layer, and a first horizontal alignment film that is in contact with the liquid crystal layer,
• the second substrate includes a second horizontal alignment film that is in contact with the liquid crystal layer,
• the retardation layer includes a λ/4 plate and a λ/2 plate,
• the liquid crystal layer includes a positive-type liquid crystal material or a negative-type liquid crystal material, and has a twist alignment when no voltage is applied,
• an angle formed by a polarization axis of the polarizer and an alignment direction of liquid crystal molecules defined by the first horizontal alignment film is 63.5° or more and 71.5° or less when the liquid crystal layer includes the positive-type liquid crystal material, and
• the angle formed by the polarization axis of the polarizer and the alignment direction of the liquid crystal molecules defined by the first horizontal alignment film is 20.5° or more and 26° or less when the liquid crystal layer includes the negative-type liquid crystal material.
