Display device

An electronic device including a display device, the display device including a folding region foldable with respect to a virtual folding axis which extends in a first direction, and a first non-folding region and a second non-folding region, which are spaced apart in a second direction which is perpendicular to the first direction with the folding region disposed therebetween, the display device comprising:

• a display module including a folding display portion corresponding to the folding region, a first non-folding display portion corresponding to the first non-folding region, and a second non-folding display portion corresponding to the second non-folding region;
• and
• a support plate disposed below the display module and including a folding support portion corresponding to the folding region, a first non-folding support portion corresponding to the first non-folding region, and a second non-folding support portion corresponding to the second non-folding region, and including a plurality of sub-support plates stacked in a thickness direction,
• wherein the plurality of sub-support plates each include:
• a matrix portion;
• a plurality of first fibers dispersed in the matrix portion, extending in the first direction, and spaced apart in the second direction;
• and
• a plurality of second fibers dispersed in the matrix portion, disposed above or below the first fibers and extending in the second direction, and spaced apart in the first direction, wherein
• a number of first crossing points in which the first fibers and the second fibers cross per unit area at a portion corresponding to the folding support portion is smaller than a number of second crossing points in which the first fibers and the second fibers cross per unit area at a portion corresponding to the first non-folding support portion and the second non-folding support portion.

• and
• a plurality of second fibers dispersed in the matrix portion, disposed above or below the first fibers and extending in the second direction, and spaced apart in the first direction, wherein
• a number of the plurality of first fibers disposed per unit area at a portion corresponding to the folding support portion is smaller than a number of the plurality of first fibers disposed per unit area at each of the first non-folding support portion and the second non-folding support portion.
