Abstract: An apparatus and method for measuring a pretilt angle of a liquid crystal (LC) are disclosed. The method includes irradiating polarized light on an LC cell including a first substrate, a second substrate facing the first substrate, and an LC layer between the first substrate and the second substrate. At least one of the first substrate and the second substrate includes a minute branch electrode. Irradiated light is scanned within a predetermined angle range in a direction not parallel to the minute branch electrode, an intensity of light that is transmitted through the LC cell is detected, and a pretilt angle of the LC is obtained by using a light intensity detection signal corresponding to the transmitted light.
