  • Publication number: 20230305342
    Abstract: A display device includes: a plurality of first color filters not intersecting a non-linear portion with at least a part of an outer shape of a display region being non-linear, a plurality of second color filters at least part of which intersects the non-linear portion, a first region with the plurality of first color filters disposed, a second region with the plurality of second color filters disposed, a first light blocking portion partitioning the plurality of first color filters, a second light blocking portion partitioning the plurality of second color filters, and a spacer. An overlapping area of the second light blocking portion with respect to the plurality of second color filters is larger than that of the first light blocking portion with respect to the plurality of first color filters. A distribution density of the spacer in the second region is lower than that in the first region.

  • 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.
