Embodiment Construction

[0043] (first embodiment)

[0044] First, a first embodiment of the organic EL coating device of the present invention will be described. Since the filter is installed in the nozzle, clogging of the nozzle is effectively suppressed, and therefore, the first embodiment can stably discharge the coating liquid in which the organic EL material is mixed with a prescribed solvent (hereinafter simply referred to as "organic EL material"). Material").

[0045] FIG. 1 is a diagram showing a first embodiment of an organic EL coating apparatus of the present invention. As shown in FIG. 1, the organic EL coating device is composed of the following parts: a platform 1 for receiving glass substrates S coated with red, green and blue organic EL materials 10a-10c; The platform moving mechanism 2; the position matching symbol detection part 3 which detects the position matching marks formed on the glass substrate S; the first supply part 5 which supplies the red organic EL material 10a to th...

Abstract

The invention provides a device that can stably spit out coating liquid that contains organic EL material on a base plate through a nozzle. The internal space (SP) of a nozzle body (41) that forms the nozzle (4a) has the function as a flow path that drives the organic EL material (10a) to flow. Filters (43) are arranged on the flow path and the internal position of the pores (45a) that are arranged at the front end of the nozzle. The filter fineness of the filters (43) is 10 micrometer, thus the device can be used for collecting foreign matters and gelatinous solutes, etc. to prevent the foreign matters and the gelatinous solutes from reaching the pores (45a), thereby being capable of reliably preventing the pores (45a) from being blocked up by the foreign matters, and so on.

Description

[0001] (This application is a divisional application of the application with the same name as 031465471 filed on July 7, 2003) technical field [0002] The present invention relates to an organic EL coating device and method for discharging an organic EL (electroluminescent) material onto a substrate such as a glass substrate. Background technique [0003] Such an organic EL coating device includes: a pump for taking out an organic EL material stored in a supply source; and a nozzle for discharging the organic EL material discharged from the pump from the supply source through a pipeline toward grooves formed on a substrate. The organic EL material is ejected from the nozzle toward the substrate. [0004] The organic EL material is made by dissolving the polymer solution in an organic solvent, and has the characteristic of gelling the polymer solution in the organic EL material by increasing the pressure. Because of this, the nozzle is clogged, and the organic EL material m...
