Liquid crystal display device

A liquid crystal display device including a plurality of pixels arrayed in a matrix shape, the liquid crystal display device comprising:

• a first substrate;
• a second substrate facing the first substrate;
• a liquid crystal layer provided between the first substrate and the second substrate;
• a polarizer disposed outside the first substrate or the second substrate;
• and
• a phase difference layer disposed between the first substrate and the polarizer or between the second substrate and the polarizer,
• wherein the first substrate includes a reflective layer that reflects light, a first electrode and a second electrode configured to generate a transverse electrical field in the liquid crystal layer, and a first horizontal alignment film in contact with the liquid crystal layer,
• at least one of the first electrode and the second electrode includes a plurality of belt-shaped portions and a slit located between two adjacent belt-shaped portions of the plurality of belt-shaped portions,
• in each pixel of the plurality of pixels, the plurality of belt-shaped portions has a linear shape extending substantially parallel to each other and in a same direction, and does not include a bending part,
• the second substrate includes a second horizontal alignment film in contact with the liquid crystal layer,
• the liquid crystal layer takes a twist alignment when no voltage is applied,
• the liquid crystal layer includes a positive-working liquid crystal material,
• the phase difference layer includes a λ/2 plate, and
• an in-plane slow axis of the λ/2 plate is 25° or greater and 50° or less when a direction orthogonal to a direction in which the plurality of belt-shaped portions extends is used as a reference 0°.
