US Patent 7973461 Light emitting device and display device using the same

A light emitting device and a display device using the same. The light emitting device includes: a substrate provided with recesses formed in a stripe pattern; first electrodes disposed inside the recesses in a stripe pattern aligned parallel to the recesses; electron emission regions disposed on the first electrodes; second electrodes disposed in a stripe pattern aligned in a direction crossing the first electrodes and closely fixed to the substrate; and an adhesive member for fixing the second electrodes to the substrate. The second electrodes include mesh portions spaced apart from tops of the electron emission regions in crossing of the first electrodes and the second electrodes, supports surrounding the mesh portions and connected with the substrate, and combining grooves formed at edges of the supports facing the substrate. The adhesive members are disposed in the combining grooves of the second electrodes to connect the second electrodes with the substrate.
