Optoelectronic component with a space kept free from underfiller

An optoelectronic component comprising:

• a substrate comprising:
• a first optoelectronic component;
• a second optoelectronic component arranged next to said first optoelectronic component;
• and
• a first contact point;
• a support of said substrate comprising a second contact point, wherein said second contact point is located opposite to said first contact point and is in electrical connection with said first contact point;
• an underfiller in a space between said substrate and said support;
• said underfiller forms a border area between said substrate and said support toward a space free of underfiller, wherein said border area restricts said space free of underfiller of at least one of said first and second optoelectronic components, wherein said support comprises a transparent material, and a scanning grating is positioned on said support.
