Abstract
A display panel according to the present disclosure is a display panel with which an optical pen can be used. The display panel includes: a position information pattern layer which causes the optical pen to identify a position on the display panel; a color filter layer including a color filter partitioned by a lattice structure; and a non-visible light reflection layer having a shape which diffuses and reflects a part of a non-visible light emitted from the optical pen. The non-visible light reflection layer is disposed between the position information pattern layer and the color filter layer, and an amount of light which is reflected by the non-visible light reflection layer and then enters the optical pen is larger than an amount of light which enters the optical pen through the non-visible light reflection layer after being transmitted through the color filter layer and then reflected.
