Definitions
- the present invention relates to a method for manufacturing an organic EL display.
- organic EL displays are expected as next-generation flat display panels.
- the organic EL display is self-luminous and has no viewing angle dependency, and has advantages such as high contrast, thinness, light weight, and low power consumption.
- the organic EL element constituting the organic EL display basically has a pixel electrode and a counter electrode, and an organic layer disposed between the pixel electrode and the counter electrode.
- the organic layer includes a light emitting layer containing phosphor molecules, a hole conductive thin film and an electron conductive thin film sandwiching the light emitting layer.
- organic EL displays In the production of organic EL displays, it is important to form a laminated film of organic layers. This is because the state of the organic layer greatly affects the light emission efficiency and power consumption of the organic EL display.
- the organic layer forming method is roughly divided into two types depending on whether a low molecular material or a high molecular material is selected as the organic material.
- the organic layer laminated film can be generally formed by a vacuum deposition method.
- a substrate and a small molecule organic material are set in a vacuum chamber. Then, after the chamber is evacuated, the low-molecular organic material is evaporated by resistance heating to form an organic layer on the substrate. By repeating vapor deposition for each organic material, a laminated film of organic layers can be formed.
- the laminated film of the organic layer can be formed by a coating method.
- An organic layer is formed by applying (printing) a solution containing a polymer organic material to a necessary portion by an inkjet method or the like and drying the solution. By repeating application and drying for each organic material, a laminated film of organic layers can be formed (see, for example, Patent Documents 1 to 5).
- the organic material to be a light emitting layer is different for each emission color. Therefore, the organic material must be deposited for each emission color.
- the deposition is performed in a state in which the location where the deposition is not performed is masked with a metal mask.
- a solution containing an organic material can be applied to an appropriate location without masking with a metal mask.
- the coating method does not require masking, it is advantageous as a method for forming an organic layer when manufacturing a large display.
- the solution When the organic layer is formed by a coating method such as an inkjet method, the solution must be applied so as to have a uniform film thickness over the entire surface of the substrate. However, it may be difficult to apply a uniform film thickness on the entire surface of the substrate. For example, in the case of the ink jet method, there are cases where the solution cannot be applied with a uniform film thickness on the substrate surface due to the stability of ejection from the nozzle or nozzle clogging. In addition, when there is a foreign substance on the substrate on which the application is performed, there is a possibility that the discharged solution may not be uniformly applied with a predetermined film thickness even if the discharge from the nozzle is stable.
- the uniformity of the film thickness within the substrate surface cannot be ensured, and the film thickness can be uneven within the substrate surface.
- a portion where the solution is not applied may occur. If there is a poorly formed portion in the organic layer in this way, luminance unevenness or a non-light emitting portion may occur when the display is caused to emit light. As a result, the production yield of the organic EL display is lowered.
- Patent Document 6 discloses a method for repairing a defective formation portion of an organic layer when the organic layer is formed by an inkjet method. In this method, a poorly formed part of the organic layer is detected, and a solvent is provided to the detected defectively formed part to dissolve the poorly formed part. Next, a solution containing an organic material is selectively applied to the dissolved region, and an organic layer is formed again.
- Patent Document 6 has a problem that it is impossible to repair a poorly formed part (convexly formed defective part; see FIG. 3C) whose film thickness is thicker than the surroundings. That is, the poorly formed part repaired by the method of Patent Document 6 must be thinner than the surrounding normal part so that the solvent does not spread to the surrounding normal part.
- the method of Patent Document 6 has a problem that it is difficult to control the amount of the solution to be reapplied to an appropriate amount. That is, in the method of Patent Document 6, the amount of the solution to be reapplied increases if the size of the poorly formed portion is large, and the amount of the solution to be reapplied decreases if the size of the poorly formed portion is small. As described above, since the amount of the solution to be reapplied greatly varies depending on the size of the poorly formed part, it is difficult to apply the solution by appropriately controlling the appropriate amount, and the defectively formed part may not be completely repaired. There is.
- Patent Document 7 describes a method for repairing a defectively formed part having a step of removing a defectively formed part mixed with foreign matter and the like, and a step of re-applying a solution containing an organic material in a region where the defectively formed part is removed.
- the repair method disclosed in Patent Document 7 since the formation failure portion is removed, it is possible to repair a formation failure portion of a type in which the film thickness is thicker than the surroundings.
- the amount of the solution to be reapplied may be determined according to the amount of the removed organic layer, so that the amount of the solution to be reapplied is controlled. Is possible.
- Patent Document 7 has a problem that when a solution containing an organic material is reapplied to a region where the formation failure portion has been removed, the solution spreads to places other than the formation failure portion.

- FIG. 1A in Patent Document 7, an organic layer formation defect portion 140 is formed by removing a defective formation portion of an organic layer mixed with foreign matters by laser irradiation or the like.
- the solution 150 containing the organic material is re-applied to the organic layer removing unit 140 to re-form the organic layer (FIG. 1B).
- the solution 150 may overflow from the organic layer removal unit 140 and spread to a normal part around the organic layer removal unit 140.
- the spread of the solution 150 becomes remarkable.
- FIGS. 2A and 2B are views showing a state in which the solution 150 applied to the organic layer removing unit 140 has spread to a region other than the organic layer removing unit 140.
- FIG. 2A is a perspective view
- FIG. 2B is a cross-sectional view.
- the film thickness of the organic layer 110 becomes non-uniform. If the film thickness of the organic layer is not uniform, the product quality deteriorates and the manufacturing yield decreases.
