Abstract: A light-emitting display device includes a pixel defining layer with an opening that exposes a first electrode, a hole injection layer on the first electrode, a lyophilic pattern on the hole injection layer in the opening, a hole transport layer on the lyophilic pattern, a light-emitting layer on the hole transport layer, and a second electrode on the light-emitting layer. The lyophilic pattern includes a first part adjacent to a first sidewall of the opening and a second part adjacent to a second sidewall of the opening. A distance from a top surface of the hole injection layer to an edge of a top surface of the second part corresponds to a first height. A distance from the top surface of the hole injection layer to a top surface of the first part corresponds to a second height. The first height is lower than the second height.
