Problems solved by technology

[0007] However, the method described in Patent Document 1 is to check the shape of each functional layer bouncing on the substrate by the discharge method in advance, and to dry it under a certain drying condition corresponding to the inspection result. In this method, Sometimes the shape cannot be sufficiently controlled by the coating liquid
Especially when the coating liquid contains many kinds of solvents, it is difficult to control the shape

Embodiment

[0041] As a solvent, a pigment ink containing glycerol at a ratio of 1, ethylene glycol at a ratio of 30, and water at a ratio of 70 is coated on the substrate, such as figure 1 As shown, the above-mentioned pigment ink can be dried by heating at 80°C for 5 minutes during the first drying, heating at 120°C for 3 minutes during the second drying, and heating at 180°C for 1 minute during the third drying, and a good film can be obtained. Thick distributed film. On the contrary, when the same pigment ink as the above-mentioned pigment ink is coated on a substrate and dried by heating at 120° C., heat convection is remarkably generated during the drying process, and the film thickness distribution varies in the obtained film.

Abstract

The present invention provides a liquid droplet spraying and applying method capable of obtaining a solidified object or film with a good thickness distribution when heating and drying a coating liquid, after spraying and applying liquid droplets of the coating liquid to a substrate by an inkjet application method, or the like. After spraying and applying the liquid droplets of the coating liquid containing a plurality of solvents to the surface of a material to be coated, the coating liquid applied on the surface of the material to be coated is dried by heating while sequentially elevating the heating temperature according to the respective boiling point temperatures of a plurality of the solvents.

Description

technical field [0001] The present invention relates to a display device using a thin display panel such as a semiconductor device, a liquid crystal display panel, an organic EL (electroluminescence) display panel, or a field emission display panel. A liquid droplet spray coating method used in the process of a desired film and a method of manufacturing a display device using the same. technical background [0002] In the manufacture of display devices using thin display panels such as semiconductor devices, liquid crystal display panels, organic EL (electroluminescent) display panels, or field emission display panels, by using an aqueous solution or a coating liquid containing an inorganic or organic solvent The droplets are jet-coated from an inkjet nozzle onto a substrate and then dried to form a film such as a functional layer. Such an inkjet coating method is particularly suitable for forming a film that requires a fine pattern, such as a light-emitting layer and a col...
