Abstract
A display element includes a position regulating plate along the side of a condensing lens for positioning the sides of the condensing lens, a filter and an emission element in the same plane so as to prevent any deviation in the position. The display element prevents separation between a condensing lens, a filter and the front panel of an emission element even if thermal stress or other external forces are applied to the display element as well as preventing inclination of the condensing lens when the members are bonded together.
