1. A display device comprising:
a display region comprising:
a first layer comprising a plurality of first units; and
a second layer comprising a plurality of second units and a first insulator,
wherein the second layer is placed over the first layer, and
wherein the first insulator comprises a light-transmitting and elastic material,
wherein each of the plurality of first units is smaller than each of the plurality of second units in size,
wherein the plurality of first units each comprise a first light-emitting portion,
wherein the plurality of second units each comprise a second light-emitting portion,
wherein a first one of the plurality of first units comprises a first region overlapping with two of the second units that are adjacent to each other,
wherein a second one of the plurality of first units comprises a second region overlapping with four of the second units that are arranged in adjacent two rows and two columns,
wherein an area of each of the first region and the second region is configured to be changed by stretching the first insulator,
wherein when the first insulator is stretched, a whole of the first light-emitting portion of the first one of the plurality of first units is exposed between the two of the second units that are adjacent to each other,
wherein when the first insulator is stretched, a whole of the first light-emitting portion of the second one of the plurality of first units is exposed between the four of the second units that are arranged in adjacent two rows and two columns, and
wherein an aspect ratio of the display device is changeable.
