Abstract:
A defect compensation method for a liquid crystal display apparatus having an alignment film for aligning an orientation of liquid crystal molecules, said method comprising the steps of:measuring the light transmittance of a defective pixel;irradiating said alignment film at the part of a defective pixel by a laser beam, so as to lower a molecular orientation function; therebycorrecting an amount of light emitted by said defective pixel with respect to a predetermined amount of incident light;measuring the light transmittance of said defective pixel again after the irradiation of said laser beam;calculating an optimum irradiation condition based on the result of said after-irradiation measurement; andrepeating the irradiation of the laser beam and the measurement of the light transmittance until the predetermined light transmittance is obtained.
