Abstract:
1. A light emitting device, comprising: a first substrate having an illuminating member thereon; a protective layer covering the illuminating member and having a first coefficient of thermal expansion; a second substrate disposed over the protective layer; a buffer member disposed between the first and second substrates and surrounding the protective layer, wherein the buffer member has a second coefficient of thermal expansion which is less than the first coefficient, wherein the buffer member comprises a polymeric resin and a plurality of inorganic oxide particles dispersed in the polymeric resin, wherein the inorganic oxide particles has a concentration of about 20% to about 80% by weight of the buffer member; and a sealant disposed between the first and second substrates and surrounding the buffer member, wherein the sealant has a third coefficient of thermal expansion which is less than the second coefficient, wherein the concentration of the inorganic oxide particle has a maximum value at an end position in contact with the sealant.
