Abstract
A spill light removing device includes a first blocker which is located perpendicularly to a stream route of light being irradiated from a light source and blocks a stream of light that is incident to the surface of the first blocker, except on a hole formed on the first blocker; a pass-through tunnel which is connected to the hole and is formed in the same direction to the stream route of light and allows the stream of the light to pass through; and a second blocker which has a irregularity pattern that is formed on a inner wall of the pass-through tunnel and reflects the light that is incident in the deviated direction of the stream route of light.
