Abstract
Abstract A liquid crystal display apparatus is constituted by using (a) a liquid crystal panel (100) comprising a pair of substrates (101-102) each provided with an electrode and a liquid crystal disposed between the substrates in combination with (b) a supporting member (107) having a frame for supporting the liquid crystal panel. The liquid crystal panel is fixed in a floating state to the frame of the supporting member (107) by the medium of (c) an elastic member (115) so as to define an almost closed space (117) defined by the liquid crystal panel, the supporting member (107) and the elastic member (155). The almost closed space (117) functions to suppress a deleterious flexural deformation of the liquid crystal panel in response to external mechanical forces, such as dropping impact and vibration, and also provides a good heat efficiency when it is used in combination with a planar heater for heating the liquid crystal panel.
