ABSTRACT:
In a liquid crystal display device (LCD), a spacer is interposed between an upper and a lower substrate implemented by flexible films. Liquid crystals are confined in the gap between the two substrates. The spacer is scattered in the crystals at a density higher than 201/mm.sup.2 and lower than 800/mm.sup.2. The device allows a minimum of bubbles to be produced in the crystals without resorting to gas barrier coatings or similar conventional implementation against bubbles. When the spacer is sprayed, it is uniformly distributed to set up a uniform cell gap. The device is, therefore, free from display speckles and other defects and inexpensive.
