Abstract
A liquid crystal device is constituted by a pair of substantially parallel substrates disposed opposite to each other to leave a gap extending two-dimensionally therebetween including a rectangular wider gap region and a peripheral frame-shaped narrower gap region surrounding the wider gap region, a plurality of spacers disposed in the gap over the wider and narrower gap regions, and a liquid crystal disposed between the pair of substrates so as to form pixels in the wider gap region. The spacers are disposed to have a larger volume per unit substrate area in the wider gap region and a smaller volume per unit substrate area in the narrower gap region, thus providing a uniform cell gap between the substrates.
