Abstract
A belt-shaped sealant is coated on a substrate to surround a periphery of a display region of a flat type display device. A start point and a termination point of the sealant are disposed remote from the display region such that the sealant never intrudes into the inside of the display region when the sealant is pressed between opposing substrates of the display device.
Claims5
A method for manufacturing a flat type display device comprising the steps of:
- coating a sealant on at least one of two opposing substrates so as to surround a display region in such a manner that a start point and a termination point of said sealant are displaced from said display region toward a periphery of said at least one of two opposing substrates, said start point and termination point being defined such that coating of said sealant begins at said start point and terminates at said termination point;
- and
- adhering said two opposing substrates to each other to form a closed loop consisting of said sealant with a recess formed in an inner periphery of said closed loop.
A method for manufacturing a flat type display device comprising the steps of:
- coating a sealant having a constant width on at least one of two opposing substrates so as to dispose said sealant on a portion of said at least one of two opposing substrates apart a predetermined distance from a periphery of said at least one of two opposing substrates;
- and
- adhering said two opposing substrates to each other to form a closed loop consisting of said sealant,
- said method being further constructed such that a start point and a termination point of said sealant are displaced from said closed loop toward a periphery of said at least one of two opposing substrates so as not to form a projection intruding into an inner periphery of said closed loop, said start point and termination point being defined such that coating of said sealant begins at said start point and terminates at said termination point.
