Abstract
A patterned light guide structure includes a transparent substrate with a first side and with a second side, an anti-reflective layer directly attached to the first side, a first light-shielding layer directly disposed on the anti-reflective layer, a second light-shielding layer directly disposed on the second side, and a protecting layer directly disposed on the first light-shielding layer to keep the first light-shielding layer from any deteriorating damage.
