A liquid crystal display device having an upper electrode layer and a lower electrode layer formed on an identical substrate via an insulating layer includes slits formed on the upper electrode layer for applying voltage between the upper electrode layer and the lower electrode layer and driving liquid crystal molecules. The outer surface of the instrument is adorned with a wood veneer for a finished look that resembles a traditional instrument, such as a guitar. The mixed organic solvent supplying step is a step of supplying a fluid of a mixed organic solvent to the main surface of the substrate after the cleaning processing step. The packaging signal of the invention can be used to transmit genetic material for gene therapy, cell therapy, or other biotechnological applications. The edited floor plan is then evaluated to determine whether the mark overlaps any fixed shapes andor restricted-use areas. The graphical indicator may further show a proportion of the number of unseen messages to the total number of messages.
