The upper substrate includes an upper polarizer (143) and a color filter layer (127), the upper polarizer being an extraordinary type polarizer. The lower substrate includes a reflective film (119).

A plurality of curved first protrusions (211) and a plurality of curved second protrusions (221) are disposed at insides of the substrates respectively. When an electric field is applied between the substrates, the liquid crystal molecules tend to be oriented parallel to the substrates. In addition, the curved protrusions affect the orientations of the liquid crystal molecules, such that the liquid crystal molecules are directed to incline in various directions in smooth continuums. The visual effect of the continuous domain vertical alignment liquid crystal display is the sum of multiple smooth continuous domains. Thus the continuous domain vertical alignment liquid crystal display provides a more even display performance at various different viewing angles.
