Abstract:
The purpose of the present invention is to provide a display apparatus whereby 3D display and 2D display can be switched using a simple structure. This display apparatus comprises: a panel (11) that has an arrangement of a plurality of pixels and displays an image; a microlens array (20) positioned on a display-surface side of the panel (11), the microlens array having a first electrode (23) in which a plurality of openings (24) are formed, a transparent electrode (21) facing the first electrode (23), and a dielectric polymer material (22) positioned between the first electrode (23) and the transparent electrode (21); and a control device for controlling application of a voltage to the microlens array (20). The control device controls the voltage applied to the microlens array (20) and controls generation of microlenses (25) in the openings (24), thereby switching between three-dimensional display and two-dimensional display.
