Abstract

The invention discloses an electroluminescence device and a manufacturing method thereof and relates to the display field. The reliability of electric connection of a thin film transistor and a second electrode is ensured, and in the meanwhile, film forming time can be shortened, the etching difficulty can be reduced and accordingly the production efficiency can be improved in the connecting electrode manufacturing process. The electroluminescence device comprises a color film substrate and an array substrate. The array substrate comprises a first substrate, a thin film transistor, a first protective layer and a first connecting electrode connected to a drain electrode of the thin film transistor, wherein the thin film transistor, the first protective layer and the first connecting electrode are sequentially arranged on the first substrate. The color film substrate comprises a second substrate, a first electrode, an organic light-emitting layer and the second electrode, wherein the first electrode, the organic light-emitting layer and the second electrode are arranged on the second substrate. The second electrode is connected with the first connecting electrode through a conductive adhesive.

Description

Technical field [0001] The invention relates to the field of display, in particular to an electroluminescence device and a preparation method thereof. Background technique [0002] Organic Light Emitting Diode (OLED), also known as Organic Electroluminescence Display (OELD), is self-luminous at the same time, does not require a backlight, high contrast, thin thickness, wide viewing angle, fast response speed, The excellent characteristics of wide operating temperature range, simple structure and manufacturing process have recently been widely used in mobile communication terminals, personal digital assistants (PDAs), handheld computers, etc. [0003] OLED devices are divided into passive matrix type and active matrix type OLED devices. The active matrix type OLED means that each OLED is controlled by a thin film transistor (TFT) circuit to control the current flowing through the OLED and has luminous efficiency. High and good image display characteristics. [0004] Such as figure 1...
