Abstract
A hermetic container used by an image display apparatus or the like is constituted of confronting substrates which are fixed together by a reinforcing member, and an inner space between the substrates is sealed by a sealing member. The reinforcing member is spaced apart from the sealing member to prevent breakage of the hermetic container to be caused by a difference between thermal expansion coefficients of materials.
Claims4
A hermetic container, comprising:
- a first substrate;
- a second substrate disposed confronting with said first substrate;
- an outer frame disposed between said first and second substrates and surrounding a space between said first and second substrates;
- a sealing member for sealing a connection area between said outer frame and at least one of said first and second substrates, a space defined by said first and second substrates and said outer frame being maintained hermetic;
- and
- a reinforcing member disposed outside the space maintained hermetic and between said first and second substrates, said reinforcing member maintaining a fixed state of a relative position of said first and second substrates,
- wherein:
- said reinforcing member does not contact an area at which said outer frame and said sealing member contact mutually, and
- said reinforcing member consists of an adhesive for adhering said first and second substrates,
- wherein said reinforcing member, said outer frame and said sealing member have different thermal expansion coefficients.
