Abstract:
A liquid crystal display device includes first and second substrates, a liquid crystal layer sandwiched between the first and second substrates, a pixel electrode formed on the first substrate, and a counter electrode formed on the second substrate. A plurality of projected portions are formed on the second substrate in a pixel area. The plurality of projected portions includes a first projected portion and a second projected portion, and the first projected portion is longer than the second projected portion in the pixel area.
