Abstract

A light sensing device is disclosed. The light sensing device includes a first light sensor and a second light sensor. The first light sensor formed on a substrate includes a first metal oxide semiconductor layer for absorbing a first light having a first waveband. The second light sensor formed on the substrate includes a second metal oxide semiconductor layer and an organic light-sensitive layer on the second metal oxide semiconductor layer for absorbing a second light having a second waveband.
