Title:
GAS BARRIER FILM, METHOD FOR PRODUCING THE SAME, POLARIZING PLATE WITH GAS BARRIER LAYER AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/153307
Kind Code:
A1
Abstract:
A gas barrier film (10) has a transparent film substrate (11) and a gas barrier layer (12). The gas barrier layer (12) includes a silicon oxycarbide layer (13). The silicon oxycarbide layer (13) includes a first layer (14), a second layer (15), and a third layer (16). The carbon content in the first layer (14) and the carbon content in the third layer (16) are less than 0.1 at%. The carbon content in the second layer (15) is at least 0.1 at%. The thickness percentage of the second layer (15) is 20-70%. Regarding the silicon oxycarbide layer (13), when the carbon content at a location where the carbon content is found to be greatest is noted as Cmax at%, and the carbon content at a location where the carbon content is found the smallest is noted as Cmin at%, the value obtained by subtracting Cmin from Cmax is 6.0 or less.
