Array substrate and light field display device

A light field display device, comprising:

• an array substrate, the array substrate comprising a substrate, a plurality of electrodes, and a plurality of first signal lines;
• and
• a power supplying circuit, wherein
• the plurality of electrodes and the plurality of signal first lines are disposed on the substrate;
• each of the plurality of electrodes is connected to one of the plurality of first signal lines;
• the plurality of first signal lines extends along a first direction;
• at least two first signal lines of the plurality of first signal lines are located in different layers of an insulating spacer from each other;
• and
• orthographic projections on the substrate of the at least two first signal lines in the different layers at least partially overlap.

A method for fabricating a display for a light field display device, the method comprising:

• disposing a plurality of signal lines on a substrate;
• disposing a plurality of electrodes on the substrate;
• and
• connecting the plurality of electrodes to the plurality of signal lines, wherein
• the plurality of signal lines extends in a single direction;
• at least two first signal lines of the plurality of signal lines are located in different layers of an insulating spacer from each other;
• and
• orthographic projections on the substrate of the at least two signal lines in the different layers at least partially overlap.
