A planar display assembly is provided with a planar display pane. A frame is provided with a dado sized to receive the planar display pane. A plurality of retainers mounts to the frame about an inner periphery of the frame to retain the planar display pane within the frame. At least one of the plurality of retainers is elastically deformable to deform during installation of the planar display into the frame, and to expand to retain the planar display pane within the frame. A plurality of apertures or a channel may be formed in the frame about the dado. The plurality of retainers may mount to the frame within the plurality of apertures or the channel of the frame to retain the planar display pane within the frame.
