Abstract
Abstract A display apparatus includes a display cell having a plurality of electrodes, a cell-supporting member for supporting the display cell, and a circuit substrate connected to the display cell for driving the display cell. The circuit substrate is supported for limited movement; relative to the cell-supporting member by a holding plate. The holding plate may preferably be composed of a plate spring for pressing the circuit substrate against the cell-supporting member.
