ABSTRACT:
In a display apparatus that has a polymer dispersed liquid crystal material25encapsulated in a gap between a completed first substrate1and a completed second substrate11by using a sealing member26and has a display region M and a peripheral region N in a region where the polymer dispersed liquid crystal material25is encapsulated, a wiring electrode19having light shielding properties is provided in at least a part of the peripheral region N of the completed second substrate11, and an ultraviolet ray transmitting portion19athat transmits an ultraviolet ray therethrough is provided in the peripheral region where the wiring electrode19is provided. An ultraviolet ray is applied from the substrate side where the ultraviolet ray transmitting portion19ais provided to polymerize a monomer in the peripheral region N. The ultraviolet ray transmitting portion is formed of, e.g., a plurality of small holes, and the small holes are dispersedly arranged at equal intervals.
