Abstract
Provided is a display panel using polymer network liquid crystal in which a monomer unreacted region is reduced and a thin-film transistor can be prevented from being irradiated with light energy. In the display panel, a black matrix () is provided as an element having a light-shielding property in a first substrate (), a pixel electrode () and a thin-film transistor () serving as a switching element for driving the pixel electrode () are provided in a second substrate (), polymer network liquid crystal () is filled between the first substrate () and the second substrate (), a cover portion () that is part of the black matrix () provided in the first substrate () faces the thin-film transistor () provided in the second substrate (), and the outer periphery of the cover portion () is located outside the outer periphery of a channel region by a specified dimension or more.
