METHOD FOR MANUFACTURING THIN-FILM DEVICE, LIQUID CRYSTAL DISPLAY APPARATUS, AND ELECTROLUMINESCENCE DISPLAY APPARATUS

摘要

PROBLEM TO BE SOLVED: To cut laminated substrates after an active substrate and a counter substrate are laminated, without cutting one of the substrates, by preliminarily forming an aperture that penetrates the thickness direction of the counter substrate at the desired position of the counter substrate.

SOLUTION: The method for manufacturing a thin film device includes the steps of: forming a thin film device layer 12 on a first substrate 11; forming an aperture 22 penetrating in the thickness direction in a second substrate 21; aligning the first substrate 11 and the second substrate 21; and completely or partially separating or removing at least one substrate of the aligned substrates by a step, including at least one treatment of chemical treatment, polishing treatment and UV irradiation treatment.
