The optoelectronic device (10) has: a first conductive contact layer (101), an electrical insulating layer (102) on the first conductive contact layer (101), a second conductive contact layer (102) on the electrical insulating layer (102) 103), a first conductive electrode layer (20) on the second conductive contact layer (103), at least one optically functional layer structure (22) on the first conductive electrode layer (20), and an optically functional layer structure ( 22) on the second conductive electrode layer (23). The second conductive contact layer (103) has a first recess (110). The electrically insulating layer (102) has a second recess (111) overlapping the first recess (110). Conductive via contacts ( 112 ) are arranged in the first recess ( 110 ) and in the second recess ( 111 ), which are led to the first electrically conductive contact layer ( 101 ). The conductive via contact (112) is electrically insulated from the second conductive contact layer (103).

Description

technical field [0001] The invention relates to an optoelectronic component having at least one optically functional layer structure and a method for producing such an optoelectronic component. Background technique [0002] The light-emitting optoelectronic component may be, for example, a light-emitting diode (LED) or an organic light-emitting diode (OLED). OLEDs can have an anode and a cathode with an organic functional layer system between them. Organic functional layer systems can have one or more emitter layers (where electromagnetic radiation is generated), respectively two or more carrier pair generation layers for carrier pair generation ("charge generation layers", CGL ), and one or more electron blocking layers, also known as hole transport layers ("hole transport layer" - HTL), and one or more hole blocking layers, Also known as the electron transport layer ("electron transport layer" - ETL) in order to regulate the passing current.

AI Technical Summary

Problems solved by technology

[0007] Conventional optoelectronic devices also have the disadvantage that they cannot be directly electrically contacted after their manufacture due to their electrically insulating thin-film encapsulation deposited over their entire surface

An optoelectronic inspection of the function of the optoelectronic component as quickly as possible in the production method is therefore disadvantageously not possible

The optoelectronic failure of the optoelectronic component is thus processed further in an unknown manner after its production, which disadvantageously results in additional production costs

[0008] In addition, the contact areas usually used for external electrical connections reduce the active area of ​​the optoelectronic component proportionally and disadvantageously prevent a frameless arrangement of several optoelectronic components side by side laterally to form an optoelectronic component
