Display device, and method of producing display device
A pattern of ink applied to a display region is stabilized, and unevenness in thickness of the ink in the display region is reduced. A substrate has a hole which causes ink to be drawn into the hole, the hole has a third taper which is formed in a stepwise shape having a plurality of steps and which extends in a direction perpendicular to a direction in which the ink flows into the hole, and an angle of a tangential line connecting respective vertices of the plurality of steps of the third taper is shallower than (i) an angle of a first taper which is located on a side of the hole on which side the ink flows into the hole and (ii) an angle of a second taper which is located on a side of the hole on which side the ink is pushed out from the hole.
