Abstract

A semiconductor device is provided. The semiconductor device includes a substrate and a light-collimating layer. The substrate has a plurality of pixels. The light-collimating layer is disposed on the substrate, and the light-collimating layer includes a transparent material layer, a first light-shielding layer, a second light-shielding layer and a plurality of transparent pillars. The transparent material layer covers the pixels. The first light-shielding layer is disposed on the substrate and the first light-shielding layer has a plurality of holes corresponding to the pixels. The second light-shielding layer is disposed on the first light-shielding layer. The transparent pillars are disposed in the second light-shielding layer.
