Zusammenfassung: | An over-voltage protection device is provided. According to one embodiment of the present invention, the over-voltage protection device includes: a first substrate which is provided with a first intermediate electrode and a third intermediate electrode formed on both sides of one surface thereof, and includes a first electrode extended from the first intermediate electrode; a second substrate which is provided with a second intermediate electrode and a fourth intermediate electrode on both sides of one surface thereof facing the first substrate, extended from the fourth intermediate electrode facing the third intermediate electrode, and including a second electrode of which an end part faces a part of the first electrode; and an adhesive member which is disposed between the first substrate and the second substrate to bond the first substrate and the second substrate, and has a penetration hole at a location where the first electrode and the second electrode faces each other. For the first electrode and the second electrode, a curved convex part is respectively formed on the extended end part, and for the second intermediate electrode and the third intermediate electrode, a curved recess part corresponding to the convex part is respectively formed on sides of the first electrode and the second electrode. According to the present invention, it is possible to uniformly form an air gap so that change in driving voltage during continuous use can be prevented.
과전압 보호소자가 제공된다. 본 발명의 일 실시예에 따른 과전압 보호소자는 일면의 양측에 제1중간전극 및 제3중간전극이 형성되며, 제1중간전극으로부터 연장 형성되는 제1전극을 포함하는 제1기판; 제1기판을 마주보는 일면의 양측에 제2중간전극 및 제4중간전극이 형성되며, 제3중간전극과 마주보는 제4중간전극으로부터 연장 형성되되, 제1전극의 단부와 일부가 마주보는 제2전극을 포함하는 제2기판; 및 제1기판과 제2기판 사이에 배치되어 제1기판과 제2기판을 접착하되, 제1전극과 제2전극이 서로 마주보는 위치에 관통구가 형성되는 접착부재;를 포함한다. 여기서, 제1전극 및 제2전극은 연장 형성되는 단부에 곡선 형상의 볼록부가 각각 형성되며, 제2중간전극 및 제3중간전극은 제1전극 및 제2전극 측에 볼록부에 대응하는 곡선 형상의 오목부가 각각 형성된다. |
