光層とする方法が注目されている。The light-emitting display using the organic EL material is a promising technology in the future, but has a problem in the case of achieving full color. That is, blue,
The problem was how to separate green and red separately. Here, there is a method in which a bank is formed on the electrode by lithography, a solution in which blue, green, and red organic EL materials are dissolved is discharged using a discharge device into the bank, and the solvent is removed by drying to form a light emitting layer. Attention has been paid.

る。Conventionally, a bank was formed by photolithography, but in this case, it was difficult to form a very deep bank. Therefore, it is necessary to increase the concentration of the organic EL material discharged by the discharge device. However, if the density is too high, there is a disadvantage that the discharge device is clogged. The present invention has been made to solve such a problem, and its purpose is to create a bank that separates a light emitting layer by a simple method that does not use a photolithography method. The purpose of the present invention is to provide a method that can form a deep bank and a deep bank. As a result, an object of the present invention is to realize a light-emitting display capable of full-color display using an ejection device efficiently and at low cost.
