A method of fabricating a light emitting display device comprising: providing a first mother substrate comprising a plurality of unit display panels disposed thereon, first scribe lines disposed between homogeneous regions of adjacent display panels, and second scribe lines disposed between heterogeneous regions of adjacent display panels, wherein each unit display panel comprises a pixel region comprising a plurality of light emitting diodes formed therein and a non-pixel region surrounding the pixel region comprising a pad portion formed therein; applying a seal around a circumference of the pixel region and over the first scribe lines; disposing a second mother substrate on the first mother substrate, wherein the second mother substrate comprises first scribe lines and second scribe lines corresponding to the first scribe lines and second scribe lines of the first mother substrate; curing the seal to couple the second mother substrate to the first mother substrate; and cutting the coupled first mother substrate and second mother substrate along the first and second scribe lines to separate the first mother substrate and the second mother substrate into individual unit display panels; wherein the homogeneous regions are between adjacent organic light emitting diodes of adjacent displays, and the heterogeneous regions are between the pad portion and the organic light emitting diode of adjacent displays; characterised in that portions of the seal extend along sides of the pad portion, wherein curing the seal comprises disposing a mask on the pad portion; and in that the method further comprises: cutting and removing a portion of the second substrate disposed on the pad portion, thereby exposing the pad portion of the unit display panel after separating the coupled first mother substrate and second mother substrate into individual unit display panels; and removing the seal from the non-pixel region of the pad portion. providing a first mother substrate comprising a plurality of unit display panels disposed thereon, first scribe lines disposed between homogeneous regions of adjacent display panels, and second scribe lines disposed between heterogeneous regions of adjacent display panels, wherein each unit display panel comprises a pixel region comprising a plurality of light emitting diodes formed therein and a non-pixel region surrounding the pixel region comprising a pad portion formed therein; applying a seal around a circumference of the pixel region and over the first scribe lines; disposing a second mother substrate on the first mother substrate, wherein the second mother substrate comprises first scribe lines and second scribe lines corresponding to the first scribe lines and second scribe lines of the first mother substrate; curing the seal to couple the second mother substrate to the first mother substrate; and cutting the coupled first mother substrate and second mother substrate along the first and second scribe lines to separate the first mother substrate and the second mother substrate into individual unit display panels; wherein the homogeneous regions are between adjacent organic light emitting diodes of adjacent displays, and the heterogeneous regions are between the pad portion and the organic light emitting diode of adjacent displays; characterised in that portions of the seal extend along sides of the pad portion, wherein curing the seal comprises disposing a mask on the pad portion; and in that the method further comprises: cutting and removing a portion of the second substrate disposed on the pad portion, thereby exposing the pad portion of the unit display panel after separating the coupled first mother substrate and second mother substrate into individual unit display panels; and removing the seal from the non-pixel region of the pad portion. cutting and removing a portion of the second substrate disposed on the pad portion, thereby exposing the pad portion of the unit display panel after separating the coupled first mother substrate and second mother substrate into individual unit display panels; and removing the seal from the non-pixel region of the pad portion.
