The other components and their functions are the same or similar. Accordingly, other identical components and their functions are not described in detail.
As shown in fig. 7, thedisplay device 100 and theframe area 103 are sized such that, when thedisplay device 100 is bent toward the first surface around thefirst folding portion 111, thefirst display unit 101 is shielded, neither thefirst camera module 104A nor thesecond camera module 104B is shielded, and thefourth display portion 102A and thefirst camera module 104A face the first direction. Similarly, when the foldeddisplay device 100 is viewed along the first direction or the second direction, a display portion (thefourth display portion 102A or thefifth display portion 102B) can be seen.
As shown in the figure, thedisplay device 100 and theframe area 103 are sized such that, when thedisplay device 100 is bent toward the first surface around thesecond folding portion 112, thefirst display unit 101 is shielded, neither thefirst camera module 104A nor thesecond camera module 104B is shielded, and thefifth display portion 102B and thesecond camera module 104B face the first direction. Similarly, when the foldeddisplay device 100 is viewed along the first direction or the second direction, a display portion (thefourth display portion 102A or thefifth display portion 102B) can be seen.
In addition, although not shown, it should be appreciated that when thedisplay device 100 is bent toward the second surface around thefirst folding portion 111 or thesecond folding portion 112, thesecond display unit 102 is shielded, and one of thefirst camera module 104A and thesecond camera module 104B is not shielded. When the foldeddisplay device 100 is viewed along the first direction or the second direction, thefirst display portion 101A or thethird display portion 101C can be seen. Thus, thefirst display unit 101A and thethird display unit 101C, and thefirst camera module 104A or thesecond camera module 104B are used in cooperation with each other, and thus, the need for taking front and rear images can be satisfied even if the images are not reversed.
