In a conventional optical sheet, static electricity is generated when a protective sheet is peeled, dust is stuck to the optical sheet and the appearance of a display device is impaired. However, in the optical sheet, since movement of an electrostatic charge is suppressed by air with which gaps except the sticking points are filled up because of the existence of the static charge and deformation preventing projecting parts 32, generated static electricity is still in a weak state, so that the static electricity is not apparently generated.  <P>COPYRIGHT: (C)2011,JPO&INPIT
