a stream of the light that is incident to the surface of the first blocker, except to 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 the light
and allows the stream of the light to pass through;
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.
