ABSTRACT:
In a liquid-crystal-display panel (1) for displaying a barcode that is formed with bars having various widths arranged in parallel at various intervals by an electro-optic effect of liquid crystal, a direction of a transmissive axis (P1) of a polarizing film disposed on a side on which light from a barcode reader is irradiated is set to coincides with a direction in which the light is polarized. Moreover, the direction of transmissive axis (P1) of the polarizing film is set to be parallel or substantially parallel to a short side or a long side of each of the bars forming the barcode. A direction (M) of a long axis of a liquid crystal molecule (LCM) in a first ferroelectric state or in a second ferroelectric state is set to be parallel or substantially parallel to the direction of transmissive axis (P1) of the polarizing film, or set to form an angel of 45 degrees or substantially 45 degrees therebetween.
