A display panel including auxiliary wiring on a substrate, pixel electrodes in a matrix above the substrate with gaps between the pixel electrodes, light emitting layers above the pixel electrodes, a functional layer above and continuous across the light emitting layers, and a common electrode above and continuous across the functional layer. The auxiliary wiring extends in plane directions of a main surface of the substrate below the pixel electrodes. Above the substrate, connection areas CA exist where the pixel electrodes are not present, in which the common electrode and the auxiliary wiring are electrically connected to each other. In plan view, portions of outer edges of the pixel electrodes facing outer edges of the connection areas CA are recessed inwards of the pixel electrodes.

Self-luminous display panel and self-luminous display panel manufacturing method

A brush scrubbing apparatus is made up of a wafer holder which retains a wafer, a brush which removes a particle on the wafer, a driver which rotates at least one of the wafer holder and the wafer, an alignment mechanism which defines a relative position between the brush and the wafer holder, and controller which controls the alignment mechanism responding to a driving power supply voltage in the driver. The brush scrubbing apparatus can precisely get the reference position for deciding the pushing distance without using the eye measurement.
