Method of manufacturing an organic EL display device
View Patent ↗A method of manufacturing an organic EL display device includes disposing a second base material that is disposed to face a first base material having a display region and including a TFT layer on a supporting substrate that supports the second base material, disposing the first base material on a side opposite to a side where the supporting substrate of the second base material is disposed, disposing a dam material that surrounds the display region between the first base material and the second base material, filling an inside of the dam material with a filling material between the first base material and the second base material, disposing an auxiliary wall to be separated from an outside of the dam material between the first base material and the second base material, and cutting the second base material through the supporting substrate between the dam material and the auxiliary wall.
1. A method of manufacturing an organic EL display device, the method comprising:
disposing a second base material that is disposed to face a first base material having a display region and including a TFT layer on a supporting substrate that supports the second base material;
disposing the first base material on a side opposite to a side where the supporting substrate of the second base material is disposed;
disposing a dam material that surrounds the display region between the first base material and the second base material;
filling an inside of the dam material with a filling material between the first base material and the second base material;
disposing an auxiliary wall to be separated from an outside of the dam material between the first base material and the second base material;
cutting the second base material through the supporting substrate between the dam material and the auxiliary wall; and
forming a protrusion portion in a region of the first base material where the auxiliary wall is disposed, the protrusion portion protruding toward the side where the second base material is disposed.
2. The method of manufacturing an organic EL display according to claim 1 , further comprising:
making a peeling agent be present in a space between protrusion portions which are adjacent to each other.
3. A method of manufacturing an organic EL display device, the method comprising:
disposing a second base material that is disposed to face a first base material having a display region and including a TFT layer on a supporting substrate that supports the second base material;
disposing the first base material on a side opposite to a side where the supporting substrate of the second base material is disposed;
disposing a dam material that surrounds the display region between the first base material and the second base material;
filling an inside of the dam material with a filling material between the first base material and the second base material;
disposing an auxiliary wall to be separated from an outside of the dam material between the first base material and the second base material;
cutting the second base material through the supporting substrate between the dam material and the auxiliary wall; and
forming a peeling layer in a region of the first base material where the auxiliary wall is disposed,
wherein the peeling layer includes an organic EL layer.
