A light emitting display device comprises a substrate, a circuit layer having a thin film transistor and an auxiliary power electrode disposed on the substrate, an insulating layer disposed on the circuit layer and including a first opening which exposes a portion of the auxiliary power electrode, a pixel electrode disposed on the insulating layer and connected to the thin film transistor, an auxiliary electrode contact area formed in the insulating layer, an auxiliary electrode formed on the insulating layer, a light emitting layer disposed on the pixel electrode and the auxiliary electrode, a common electrode disposed on the light emitting layer and electrically connected with the auxiliary power electrode through the auxiliary electrode contact area, a filler disposed in the auxiliary electrode contact area, and an encapsulation layer disposed on the common electrode and the filler, wherein the first opening of the insulating layer includes an undercut area between the auxiliary power electrode and the auxiliary electrode, and wherein the undercut area is filled with the filler.

Light emitting display device

The light-controlling device includes a first substrate, a second substrate and a partition wall separating the first and second substrates to define a cell. A light-adjustment medium containing a plurality of charged particles is disposed between the first and second substrates. One of the first electrode on the first substrate and the second electrode on the second substrate covers lesser area of the light-controlling device than the other electrode. The electrode covering lesser area of the light-controlling device may have grooved surface to increase the surface area without increasing the overall area of the light-controlling device covered by the electrode. Particle guidance member can be used to create a reservoir for holding increased amount of charged particles on the electrode covering lesser area of the light-controlling device.
