Embodiment Construction

[0026] Such as figure 2 As shown, the evaporation source 10 is composed of laminated frames 10A and 10B, and the frame 10A at the lowest layer forms a heating part 11, and the heating part 11 contains an organic material and heats and evaporates the organic material, while the other layer The frame body 10B forms the vapor deposition flow control part 12, and controls the direction of the vapor deposition flow from the heating part 11 toward the vapor deposition object (substrate 3).

[0027] The direction of the vapor deposition flow of the organic material vaporized by the heating unit 11 is controlled by the vapor deposition flow control unit 12 , so that only the vapor deposition flow A passing there flows toward the substrate 3 . At this time, the organic material that has not passed through the vapor deposition flow control unit 12 does not escape from the stacked frames 10A, 10B, so it is all recovered in the frame 10A at the lowest level, and the organic material of t...

Abstract

A vacuum evaporation device and a method for manufacturing an organic EL display panel using the device, the vacuum evaporation device includes an evaporation source composed of a laminated frame, the bottom layer of the frame is formed to accommodate organic materials and The heating part for heating and evaporating the organic material, and the other layer of the aforementioned frame is formed with a vapor deposition flow control part to control the direction of the vapor deposition flow from the heating part to the vapor deposition object; an organic layer forming an organic layer between a pair of electrodes A method for manufacturing an EL display panel, wherein one of a pair of electrodes is formed on the surface of a substrate; the above-mentioned vacuum evaporation device is used when the aforementioned organic layer is to be formed on the formed electrode, and the utilization of the evaporation material can be improved by using the vacuum evaporation device Efficiency; It can improve the quality of the formed film; For large-area panels, uniform evaporation can be performed.

Description

technical field [0001] The invention relates to an evaporation device, in particular to a vacuum evaporation device and a method for manufacturing an organic EL display panel with the device. Background technique [0002] As a technique for forming a thin film on a substrate, there is conventionally known a vacuum evaporation method. In this vacuum evaporation method, a substrate is arranged on the opposite side of the evaporation source in a vacuum evaporation tank, and the evaporation flow generated by the heating evaporation source is irradiated on the surface of the substrate to form an evaporation on the substrate. Thin film of material. The vacuum vapor deposition apparatus for performing the vacuum vapor deposition basically includes a vacuum chamber, a vapor deposition source, a heating / evaporating device, a substrate holder, and the like. As the heating and evaporating device, an induction heating device, which uses a material that generates heat due to electromag...
