Claim Text:
1. An evaporation device comprising: a conductive plate; an insulating plate over and in contact with the conductive plate; a first electrode over and in contact with the insulating plate, the first electrode comprising an upper surface and a first side surface; and a second electrode over the first electrode, wherein the evaporation device is configured so that the first electrode is covered by an electrode cover comprising first and second portions, wherein the first portion is configured to be in direct contact with the first side surface which faces to an evaporation source holder, wherein the second portion is configured to be in direct contact with the upper surface, to hold the evaporation source holder by sandwiching the evaporation source holder with the second electrode, and to electrically connect the evaporation source holder to the first electrode, and wherein the electrode cover is configured to fully expose a side surface of the first electrode other than the first side surface when the electrode cover covers the first electrode, wherein the electrode cover is further configured so that an outer surface of the first portion and a side surface which faces the evaporation source holder of the insulating plate exist in a coplane when the electrode cover covers the first electrode, and wherein the electrode cover is further configured so that the first portion contacts with an upper surface of the insulating plate when the electrode cover covers the first electrode.
