Abstract
A liquid crystal display element includes a pair of substrates made of plastic, a liquid crystal sandwiched between the pair of substrates, and a plurality of spacers for maintaining a gap d between the pair of substrates, which are sandwiched between the pair of substrates, and when x is an average value of thickness of the plurality of spacers in a state without a load in such a direction that the plurality of spacers are sandwiched between the pair of substrates, d<x≦1.1d is satisfied. Further, in the liquid crystal display element, a numerical density of the spacers is set to be not less than 240 pieces/mm2 and not more than 300 pieces/mm2. Further, in the liquid crystal display element, an elastic modulus of the spacers is set to be larger than that of the pair of substrates. As a result, in the liquid crystal display element, color shading is suppressed while suppressing generation of bubbles in a vacuum region and reduction in contrast, thus obtaining desirable display quality of a display image.

5. A manufacturing method of a liquid crystal display element which includes a pair of substrates made of plastic, a plurality of spacers for maintaining a gap between the pair of substrates and a liquid crystal between the pair of substrates, comprising the steps of:
-
(a) disposing said plurality of spacers between said pair of substrates, and forming a liquid crystal injection slit for injecting the liquid crystal between said pair of substrates while bonding said pair of substrates with a seal material which is provided around a region where said plurality of spacers are disposed;
(b) injecting the liquid crystal between said pair of substrates via said liquid crystal injection slit; and
