Embodiment Construction

[0096] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0097] image 3 One example of the main components of the light emitting device according to the first embodiment and its structure is shown. The light emitting device includes a light emitting part formed on a transparent substrate 10 by a multi-layer cladding formation process described below, and a thin film transistor (TFT) circuit for driving the light emitting part.

[0098] Such as image 3 As shown, the light emitting member is formed by interposing a light emitting material layer 12 made of an organic electroluminescent (EL) material between a transparent electrode 11 and a reflective electrode 13 . Light is emitted from the layer of luminescent material 12 sandwiched between these two electrodes. A part of the transparent electrode 11 is connected to a source / drain 28 . The reflective electrode 13 and the outer lead (in image 3 not shown) c...

Abstract

A light emitting device and the production method thereof are provided, which are characterized by low manufacturing costs, low power consumption, and high luminous efficiency. The production method comprises processes of forming a transparent electrode layer above a transparent substrate in order to supply current to a luminous material layer, forming the luminous material layer emitting light by supplying the current thereto on the transparent electrode layer, and forming a reflecting electrode layer on the luminous material layer in order to supply current to the luminous material layer. A plurality of opening is formed in the transparent electrode layer with a predetermined pattern. By the openings, slope sections are formed in the luminous material layer and the reflecting electrode layer. Thereby, it is possible to increase the luminous efficiency of the light emitting device.

Description

technical field [0001] The present invention relates to emitting light sources in flat panel display devices for personal digital assistants (PDAs), mobile phones, personal computers, televisions, etc., and in devices such as digital printers, scanners, facsimile machines, and digital duplicating machines Light emitting devices used in matrices and methods for their production. In particular, the present invention relates to a light emitting device capable of realizing low power consumption, low production cost and high luminous efficiency and a production method thereof. Background technique [0002] Inorganic or organic electroluminescent materials have been developed and used in light emitting devices used in flat panel displays of PDAs, cellular phones, etc., and in emitting light source matrices of digital printers. Some of these devices have already been put into practical application. There are two ways to drive these light emitting devices. One is a "passive drive...
