Abstract: A transparent display device includes a transmissive light valve panel, a transparent plate and at least one light emitting assembly. The transmissive light valve panel has a display surface. The transparent plate is disposed with respect to the transmissive light valve panel to form an optical space between the transparent plate and the transmissive light valve panel. The at least one light emitting assembly is disposed beside the optical space and adapted to generate light into the optical space. A light pattern of the light emitted from the light emitting assembly and directed to the optical space has at least one maximum peak in an angular range of ±15° with respect to a direction parallel to the display surface of the transmissive light valve panel.

Abstract: A display apparatus including a display panel and a light source module is provided. The display panel displays an image frame according to a light beam. The light source module provides the light beam to the display panel. The light source module includes a light emitting device, a lens module, a reflection device, and a light emitting surface. The light emitting device provides the light beam. The lens module is disposed in a transmission path of the light beam and adjusts the light beam to be focused or dispersed. The reflection device receives the light beam passing from the lens module and reflects the light beam to the light emitting surface. The lens module includes a lens disposed in the transmission path of the light beam and moves relative to the light emitting device to adjust a viewing angle of the light emitting surface.
