Abstract
A plurality of fixing stands (,) are attached to the inner face of a rear case (,), and a back electrode substrate (,) that functions as a back electrode and an electrode unit (,) formed by superposing a plurality of electrode plates via insulators are attached to the fixing stands (,). In this case, only one fixing stand positioned substantially at the center of the back electrode substrate (,) in the plurality of fixing stands (,) is fixed to the back electrode substrate (,), and presser bar plate springs (,) for pressing the substrate are attached onto the remaining fixing stands to fix the back electrode substrate (,) by their elasticity. Such an attachment structure enables thermal distortion in fabrication processes and during operation and influences of vibration/impacts from the exterior to be absorbed or eliminated, thus providing a flat-type image display apparatus with high accuracy and high image quality.
