Abstract:
1. A display element manufacturing method; comprising: transporting a flexible sheet substrate along a predetermined transport route by a transport apparatus; performing a first process that forms a first electrode for thin film transistors arranged corresponding to respective pixels in the display element, the first process including: forming a first surface modification layer having a repelling property with respect to a fluid material on the sheet substrate by using a first coating or printing apparatus; irradiating ultraviolet rays having a shape corresponding to the first electrode onto the first surface modification layer so as to modify a region corresponding to the first electrode from having the repelling property to having a non-repelling property by using a first exposure apparatus; and causing a first fluid material for the first electrode to be selectively disposed at the region having the non-repelling property on the sheet substrate by using a second coating or printing apparatus; performing a second process that applies a fluid material so as to form an insulating layer for the thin film transistors on the sheet substrate where the first electrode is formed; and performing a third process that forms a second electrode for the thin film transistors, the third process including: forming a second surface modification layer having a repelling property with respect to a fluid material on the sheet substrate where the insulating layer is formed by using a third coating or printing apparatus; irradiating ultraviolet rays having a shape corresponding to the second electrode onto the second surface modification layer so as to modify a region corresponding to the second electrode from having the repelling property to having a non-repelling property by using a second exposure apparatus; and causing a second fluid material for the second electrode to be selectively disposed at the region having the non-repelling property on the sheet substrate by using a fourth coating or printing apparatus.
