A full color display panel with a mirror function comprises an organic light-emitting area, a spectrum-modulation layer, a color-separating layer, a transparent substrate and a semi-reflecting layer. Each wall thickness of the opening, shoulder and bottom portions including the boss shaped bearing accommodating portion is equal to or smaller than a half of wall thickness of the magnet installation portion. machine and transferred to a deposit location. The microparticle-aggregation particles have hardness such that soiling of a thermographic printing head is low, and softness such that wear of the thermographic printing head is low. One or more communication status messages are transmitted to the charging node. When vibration is applied to the device, the error in the time-average output, which is vibration rectification error, due to this input vibration is minimized or eliminated.
