A light emitting display unit includes a redistribution layer (RDL) and multiple light emitting elements. The RDL includes multiple electrode patterns, multiple pad patterns, an insulating layer and multiple conductive through holes. A first gap and a second gap are respectively formed between two adjacent electrode patterns and between corresponding two adjacent pad patterns. A third length of the overlapping area of an orthographic projection of the first gap on the pad patterns and the pad patterns in a first direction is less than or equal to a second length of the second gap in the first direction. The micro light emitting elements are disposed on the RDL and electrically connected with the electrode patterns.
