Patent ID: 7426022

Claim:
A liquid crystal module brightness measurement apparatus, comprising: a first placement unit and a second placement unit on which a liquid crystal module is placed, a measurement unit for measuring brightness and chromaticity from an upper surface of the liquid crystal module placed on the first placement unit or the second placement unit, a placement unit moving mechanism for moving the first placement unit in an x-axis direction, a placement unit rotating mechanism for rotating the second placement unit about a predetermined axis, and a measurement unit moving mechanism for moving the measurement unit in a y-axis direction orthogonal to the x-axis direction, wherein the x-axis direction is in same direction as a shorter side direction of the liquid crystal module placed on the first placement unit, the y-axis direction is in same direction as a longer side direction of the liquid crystal module placed on the first placement unit, and the predetermined axis is an axis extending along a placement surface of the second placement unit.
