LIGHT EMITTING DEVICE

PROBLEM TO BE SOLVED: To provide a sealing structure in which effect of water invaded from the outside is suppressed, and furthermore which is enabled to obtain reliability in a light emitting device for which organic light emitting elements are used. SOLUTION: When the light emitting elements formed on a first circuit board are sealed by fixing and adhering a second circuit board with a sealing agent which is provided in the outer periphery of a first circuit board, the sealing agent is provided on the outside of electrodes of the light emitting elements, and the sealing agent is formed so as not to be overlapped with the electrodes, thereby the sealing structure to prevent invasion of water from the outside is formed. In addition, even if the sealing agent is overlapped with the electrodes, the sealing structure to prevent the invasion of water content from the outside can be formed when its contact width is 15 μm or less.
