Abstract:
1. An exposure method for a color filter substrate having: a rectangular display region which has a pair of sides extending in a first direction and a pair of sides extending in a second direction orthogonal to the first direction and in which a plurality of colored pixels and a plurality of photo spacers (PSs) are provided; a pair of first non-display regions which are respectively along the sides extending in the first direction and in which a plurality of dummy photo spacers (dummy PSs) are provided; and a pair of second non-display regions which are respectively along the sides extending in the second direction and in which a plurality of dummy photo spacers (dummy PSs) are provided, the exposure method comprising: forming a first layer included in a first dummy PS in the first non-display region by applying light, a plurality of times intermittently, on a substrate to which a photoresist has been applied while simultaneously transporting the substrate in the first direction; and forming a second layer included in a second dummy PS in the second non-display region by applying light, a plurality of times intermittently, on the substrate to which the photoresist has been applied while simultaneously transporting the substrate in the second direction, wherein the forming the first layer and the forming the second layer are carried out in an arbitrary order, and the first layer and the second layer are composed of a material different from a material of the colored pixels.
