Array substrate and fabrication method thereof, and electronic apparatus

A fabrication method of an array substrate, comprising:

• providing a base substrate;
• forming a thin film transistor on the base substrate, wherein the thin film transistor comprises a first electrode and a second electrode;
• forming a first connection electrode on the base substrate, wherein the first connection electrode is in a layer different from the first electrode and is electrically connected with the first electrode;
• and
• forming a first insulation layer covering at least a portion of the first connection electrode,
• wherein an area of an orthographic projection of the first connection electrode on the base substrate is larger than an area of an orthographic projection of the first electrode on the base substrate, and the first insulation layer is made from an organic insulation material,
• the fabrication method of the array substrate further comprises:
• forming a light emitting device on the base substrate, wherein the light emitting device is provided on the base substrate, and the first electrode is electrically connected with the light emitting device through the first connection electrode;
• and
• forming a second connection electrode, wherein
• the second connection electrode and the first connection electrode are formed by a same patterning process with a same mask, the first insulation layer further covers at least a portion of the second connection electrode, and an area of an orthographic projection of the second connection electrode on the base substrate is larger than the area of the orthographic projection of the first electrode on the base substrate;
• the light emitting device comprises a first terminal, a light-emitting layer, and a second terminal;
• the first connection electrode is electrically connected with the first terminal;
• and the second connection electrode is electrically connected with the second terminal.
