Abstract

A display apparatus includes a first panel having an electrode provided on one surface thereof, a second panel having an electrode provided on the surface thereof facing to the electrode of the first panel, display material intervened between the electrodes of the first and second panels and a spacer disposed between the first and second panels, the peripheral portions of the first and second panels being sealed by sealing material. In this case, one of the first and second panels comprises a substrate and an elastic plate which is sealed to the substrate with its periphery, and fluid is sealed into a space defined by the substrate and elastic plate with such a pressure that the elastic plate contacts the spacer.

Claims

1. A display apparatus comprising:

(a) a first panel having an electrode provided on a surface thereof;

(b) a second panel having an electrode provided on a surface thereof;

(c) display material intervened between said electrodes of said first and second panels; and

(d) a spacer disposed between said first and second panels, peripheral portions of said first and second panels being sealed by sealing material characterized in that one of said first and second panels comprises a substrate and an elastic plate which is sealed to said substrate with its periphery, and fluid is sealed into a space defined by said substrate and elastic plate with such a pressure that said elastic plate contacts said spacer.

2. A display apparatus as claimed in claim 1, wherein said fluid is air.

3. A display apparatus as claimed in claim 1, wherein said fluid contains ethylene glycol.
