Patent ID: 7876040

Claim:
An electroluminescent (EL) device comprising: a substrate having a first area and a second area, wherein the first area is included in an emissive area and the second area is included in a non-emissive area; a plurality of first transistors provided over the first area of the substrate, at least one of the plurality of first transistors having a first source, a first drain, a channel provided between the first source and drain, and a first gate provided over the channel; a plurality of light emitting elements, each of the plurality of light emitting elements coupled to a corresponding transistor of the plurality of first transistors, at least one of the plurality of light emitting elements having a first electrode, a second electrode and an electroluminescent layer provided between the first and second electrodes, and the first electrode is coupled to the first drain of a corresponding transistor of the plurality of first transistors; a plurality of second transistors provided over the second area of the substrate, at least one of the plurality of second transistors having a second source, a second drain, a channel provided between the second source and drain, and a second gate provided over the channel; at least one insulating layer provide on at least one of the plurality of first transistors or the plurality of second transistors; a first protective layer over at least one of the plurality of second transistors; and a second protective layer including a conductive layer over the first protective layer and the at least one of the plurality of second transistors, wherein the first and second protective layers are formed from one or more materials that block ultraviolet rays, and wherein the second source, the second drain, the channel provided between the second source and drain, and the second gate at the plurality of second transistors are covered with the conductive layer.
