Color filter inspection apparatus

摘要

In a color filter inspection apparatus (1), an image pickup part (13) for performing an image pickup of a color filter (9) which travels along guide rails (23) from above with a line sensor (130) and a fluorescence lamp (14) for irradiating the color filter (9) with an illumination light from below are provided and an optical filter (131) which transmits a light in a predetermined wavelength band is attached to the image pickup part (13). A transmission wavelength band of the optical filter (131) is a wavelength band in which the transmittance of one color component filter of the color filter (9) is high and transmittances of other color component filters are low. It is thereby possible to inspect unevenness in color of the color filter (9) with respect to one color component filter with high precision.
