Patent ID: 8842258

Claim:
An exposure apparatus comprising: a mask; a substrate which passes through a region disposed below the mask while moving in a first direction; a light source unit disposed above the mask, wherein the light source unit irradiates light on the substrate through the mask; and at least one blind disposed below the light source unit, wherein the at least one blind blocks the light irradiated from the light source unit, wherein a second direction is perpendicular to the first direction and in a same plane as the first direction, the at least one blind is a polyhedron having a width, a length and a thickness and is disposed such that a direction of the length is substantially parallel to the second direction, and the at least one blind is rotatable around a rotation axis substantially parallel to the second direction and which extends through the polyhedron, wherein the width of the at least one blind is greater than the thickness of the at least one blind and is less than the length, and wherein the at least one blind moves in the direction opposite to the first direction.
