Abstract: A micro-lens array includes a shutter bezel substrate, a first lens substrate having a first inner surface in contact with a first surface of the shutter bezel substrate, a first lens array disposed at a first outer surface of the first lens substrate that is opposite to the first inner surface of the first lens substrate, a second lens substrate having a second inner surface in contact with a second surface of the shutter bezel substrate, and a second lens array disposed at a second outer surface of the second lens substrate that is opposite to the second inner surface of the second lens substrate. At least one of the first lens substrate or the second lens substrate includes an alignment mark that is configured to guide placement of the first lens array on the first lens substrate and the second lens array on the second lens substrate.
