  • LIQUID CRYSTAL ELEMENT AND DISPLAY DEVICE
    Publication number: 20140078423
    Abstract: A liquid crystal panel (a liquid crystal element) 12 according to the present invention includes a pair of substrates 12a and 12b having a normal distance therebetween, a liquid crystal layer 27 arranged between the substrates 12a and 12b, a plurality of first spacers 34, and a plurality of second spacers 35. The first spacers 34 have an average particle diameter AD1 that is larger than the normal distance SD between the substrates 12a and 12b and are configured to define a distance between the substrates 12a and 12b. The second spacers 35 have an average particle diameter AD2 that is smaller than the normal distance SD between the substrates 12a and 12b and are configured to define the distance between the substrates 12a and 12b.
