Abstract
An optical sensing device is provided. The optical sensing device includes a first optical sensor and a filter layer. The first optical sensor is configured to receive a first optical signal. The filter layer covers the first optical sensor, and is configured to filter out the first optical signal when the first optical signal is incident on the filter layer at an incident angle not within a specific range.
