Abstract: A display panel of the inventive concept includes a light emitting element, a pixel circuit including a first transistor and electrically connected to the light emitting element, and a first insulating layer. The first transistor includes a first semiconductor pattern arranged under the first insulating layer and including a first source region, a first drain region, and a first channel region arranged between the first source region and the first drain region, and a first gate arranged on the first insulating layer and overlapping the first channel region. The first insulating layer includes a first region overlapping a normal region of the first gate and the first source region, and a second region which overlaps a protruding region of the first gate, has a thickness greater than that of the first region, and is disposed close to the first drain region than the first region.
