Claim:
A liquid crystal display comprising: a first substrate including a first pixel electrode and a second pixel electrode; a second substrate with an opposed electrode formed thereon, the opposed electrode opposing to the first pixel electrode and the second pixel electrode; and a liquid crystal layer sealed between the first substrate and the second substrate, a thickness of the liquid crystal layer in a first pixel region on the first pixel electrode being larger than a thickness of the liquid crystal layer in a second pixel region on the second pixel electrode; the first pixel region including a first partial region, and a second partial region where a threshold voltage is higher than in the first partial region, and the second pixel region including a third partial region and a fourth partial region where a threshold voltage is higher than in the third partial region; and the threshold voltage in the first partial region and the threshold voltage in the third partial region being equal to each other, and the threshold voltage in the second partial region and the threshold voltage in the fourth partial region being equal to each other, wherein a first electric field control structure for controlling an electric field to be applied to liquid crystal molecules of the liquid crystal layer is formed on the first substrate or the second substrate in the second partial region, a second electric field control structure for controlling an electric field to be applied to the liquid crystal molecules of the liquid crystal layer is formed on the first substrate or the second substrate in the fourth partial region, a height of the first electric field control structure being larger than a height of the second electric field control structure, and a ratio of the height of the first electric field control structure to the thickness of the liquid crystal layer in the first pixel region, and a ratio of the height of the second electric field control structure to the thickness of the liquid crystal layer in the second pixel region are equal to each other.
