Display panel, method of manufacturing the same, and substrate

A display panel comprising:

• a substrate;
• a first insulating layer provided on the substrate;
• and
• a plurality of pixels provided on the substrate, located in a display area, and including sub-pixels of a plurality of colors, respectively;
• each of the sub-pixels including:
• a drive transistor covered with the first insulating layer;
• a pixel electrode arranged on the first insulating layer, electrically connected to the drive transistor, and supplied with a signal having a current value controlled from the drive transistor;
• and
• a light emitting element mounted on the pixel electrode and including a first electrode electrically connected to the pixel electrode;
• each of the pixels including a mounting electrode arranged on the first insulating layer and located to be spaced apart from the pixel electrode,
• the mounting electrode being in an electrically floating state in a first pixel of the plurality of pixels,
• a second pixel of the plurality of pixels further includes an additional light emitting element of a first color mounted on the mounting electrode and including a first electrode electrically connected to the mounting electrode,
• in the second pixel,
• the mounting electrode is electrically connected to the drive transistor of the sub-pixel of the first color and is supplied with a signal having the current value controlled from the drive transistor, and
• when the signal having the current value controlled is supplied from the drive transistor of the sub-pixel of the first color to the pixel electrode of the sub-pixel of the first color and the mounting electrode, the light emitting element of the first color of the sub-pixel of the first color does not emit light, but the additional light emitting element of the first color emits light, and
• the second pixel further includes a wiring layer located on the first insulating layer to connect the pixel electrode of the sub-pixel of the first color with the mounting electrode.
