ORGANIC LIGHT-EMITTING DISPLAY DEVICE

An organic light-emitting display device includes a plurality of pixels (PX), each of which includes an organic light-emitting device (OLED) including a pixel electrode (310), an organic emission layer (320), and an opposing electrode (330); a pixel defining layer (150) covering an edge of the pixel electrode (310) and being configured to define a light-emission region by having an opening (150h) which exposes a portion of the pixel electrode (310); and a reference line (26) overlapping the pixel electrode (310) with an insulating layer (140) between the reference line (26) and the pixel electrode (310) and extending in a first direction. The reference line (26) overlaps with a center point (CP) of the opening (150h), and the opening (150h) is shifted to one side of the pixel electrode (310) in a second direction perpendicular to the first direction, so that a first distance (L1) between respective edge points of the pixel electrode (310) and the opening (150h) that meet a virtual reference line (VL) on the left side of the center point (CP), is different from a second distance (L2) between respective edge points of the pixel electrode (310) and the opening (150h) that meet the virtual reference line (VL) on the right side of the center point (CP), wherein the virtual reference line (VL) extends in a second direction perpendicular to the first direction.
