Embodiment Construction

[0011] Below, according to Figure 1~ Figure 8 One embodiment of the present invention will be described. FIG. 1 is a schematic perspective view showing an electroluminescent device (hereinafter referred to as "EL device"), figure 2 It is a sectional view taken along line A-A in FIG. 1 .

[0012] As shown in FIG. 1, the EL device 10 has a tube 11 as a tubular member. The tube 11 is a tube with a circular cross-section made of a light-transmitting insulating material, such as inorganic materials such as various glass materials, or polyethylene terephthalate, polyethylene naphthalate (polyethylene naphthalate). ), polypropylene, polymethyl methacrylate and other resin materials. The tube 11 of this embodiment is formed to have an inner diameter of about 5 mm and a length of about 200 mm, but not limited thereto, as long as various liquid films described later can be formed on the inner peripheral surface 11b.

[0013] On the outer peripheral surface 11a of the tube 11, as sh...

Abstract

An electroluminescence device includes a tubular first electrode, an electroluminescence layer formed on an inner surface of the first electrode, and a second electrode formed on an inner surface of the electroluminescence layer. A method for manufacturing the electroluminescence device includes: causing the inner surface of the first electrode to be lyophilic with respect to an electroluminescence layer forming liquid; conducting the electroluminescence layer forming liquid into and out of the inside of the first electrode, thereby forming a liquid film of the electroluminescence layer forming liquid on the inner surface of the first electrode, which inner surface is lyophilic with respect to the electroluminescence layer forming liquid; and forming the electroluminescence layer by drying the liquid film of the electroluminescence layer forming liquid formed on the inner surface of the first electrode. This facilitates modification of the size or the shape of the electroluminescence device and thus improves productivity for manufacturing the electroluminescence device.

Description

technical field [0001] The present invention relates to a method of manufacturing an electroluminescent device. Background technique [0002] Conventionally, fluorescent lamps, neon lamps, etc. that utilize a discharge phenomenon of a rare gas or the like sealed in a glass tube are known as rod-shaped light emitting devices. However, these light-emitting devices utilizing the discharge phenomenon have problems in that miniaturization and low power consumption are difficult. Therefore, in recent years, as a rod-shaped light-emitting device that can solve both miniaturization and low power consumption, a rod-shaped electroluminescence device (hereinafter referred to as "EL") element (hereinafter referred to as "EL") is provided on the outer peripheral surface of a rod-shaped member. "EL device" for short.) has attracted attention. [0003] In such a method of manufacturing an EL device, a method in which a first electrode (anode), an organic layer, and a second electrode (ca...
