Flat panel display with reduced display dead space

摘要

A flat display panel is provided which can improve the reliability of the contact portion where a flat plate and a back plate are bonded together and can suppress the display dead space. Recessed portions 52 are formed in a glass substrate 60 so that a sealing wall 63 is formed along the outer fringe of a back plate 61. The front plate 54 includes a protrusion 59 protruding outward from the sealing wall 63 on the outer fringe portion thereof. The contact portion between the front plate 54 and the back plate 61 is sealed by depositing fritted glass 62 onto the corner portion defined by the protrusion 59 and the side surface of the back plate 61. In order to improve the sealing effect, the fritted glass 62 is inserted into the gap at the bonding portion. The groove 64 is formed on the top surface of the sealing wall 63 to prevent the fritted glass 62 from intruding in to the discharge space.
