There is provided an organic EL display panel having a pixel circuit that
increases the panel's aperture ratio by an improved structure of a unit
pixel. The present invention discloses an organic EL display panel
including at least one pixel circuit for driving each pixel, wherein the
pixel circuit comprises at least one organic light emitting element, at
least two thin film transistors and at least one capacitor per pixel. The
thin film transistors respectively comprise a gate electrode and a
semiconductor layer in which a channel region, a source region and a
drain region are formed. The conductive layer contacted on the gate
electrode of one of the thin film transistors is coupled to another thin
film transistor and at least one capacitor.
