Bubble discharging structure, reverse printing block, display device, printing method, and method of manufacturing display device
View Patent ↗Disclosed herein is a bubble discharging structure, including a substrate which has a first area and a second area adjacent to the first area, and on which a counter substrate is caused to come in contact with the first area to provide a film having a first pattern, and a bubble discharging path through which the first area and the second area communicate with each other, and through which a bubble confined between the substrate and the counter substrate when the counter substrate is caused to come in contact with the first area is discharged from the first area to the second area.
1. A printing method, comprising:
forming a transfer layer on a counter substrate, the counter substrate having a plate shape; and
pressing said transfer layer against a first area of a substrate having said first area and a second area adjacent to said first area such that a bubble is confined between the first area and the counter substrate, the substrate having a bubble discharging path, the bubble discharging path comprising a trench formed in the substrate and extending along a portion of the substrate from the first area to the second area, the pressing thereby forming a film having a first pattern on said first area and discharging the bubble from said first area to said second area through said bubble discharging path,
wherein said first area is a display area in which pixels are provided so as to have the first pattern.
2. The printing method according to claim 1 , wherein
said first area comprises a recessed portion having a second pattern reverse to the first pattern, and
said counter substrate is a blanket in which said transfer layer is formed on a contact surface between said substrate and said counter substrate.
3. The printing method according to claim 1 , wherein
said counter substrate is a blanket in which said transfer layer comprises an organic layer having the first pattern that is formed on a contact surface between said substrate and said counter substrate.
4. A method of manufacturing a display device, comprising:
forming display elements on a substrate,
said process of forming of said display elements on said substrate including:
forming a transfer layer on a counter substrate, the counter substrate having a plate shape, and
pressing said transfer layer against a first area of a substrate having said first area and a second area adjacent to said first area such that a bubble is confined between the first area and the counter substrate, the substrate having a bubble discharging path, the bubble discharging path comprising a trench formed in the substrate and extending along a portion of the substrate from the first area to the second area, the pressing thereby forming a film having a first pattern on said first area and discharging the bubble from said first area to said second area through said bubble discharging path.
5. The method of manufacturing a display device according to claim 4 , wherein
said first area is a printing area in which a recessed portion having a second pattern reverse to the first pattern is provided, and
said counter substrate is a blanket in which said transfer layer is formed on a contact surface between said substrate and said counter substrate.
6. The method of manufacturing a display device according to claim 4 , wherein
said first area is a display area in which pixels are provided so as to have the first pattern, and
said counter substrate is a blanket in which said transfer layer comprises an organic layer having the first pattern that is formed on a contact surface between said substrate and said counter substrate.
