Patent ID: 7397174

Claim:
An image displaying apparatus comprising: a first substrate having a first conductor set as a first electric potential; a second substrate having a second conductor set as a second electric potential different from said first electric potential; an electrode plate arranged between said first substrate and said second substrate and set as a third electric potential; and a spacer which has a narrower width portion and a wider width portion, penetrates through said electrode plate at said narrower width portion, fixes said electrode plate in said wider width portion, and defines a spacing between said first substrate and said second substrate, wherein the wider width portion of said spacer is located between said first substrate and said electrode plate and the following relation is satisfied: V 1 /d 1 >V 2 /d 2 where, V 1 : electric potential difference between the first electric potential and the third electric potential V 2 : electric potential difference between the second electric potential and the third electric potential d 1 : distance between the first substrate and the electrode plate d 2 : distance between the second substrate and the electrode plate.
