Abstract

Provided is a configuration of a display device that can have a narrower frame. A display device ( 1 ) includes a first display unit ( 11 ) including a first substrate ( 111 ); a second display unit ( 12 ) including a second substrate ( 121 ) that is arranged so as to be adjacent to the first substrate ( 111 ) in an in-plane direction of the first substrate ( 111 ); a first line group ( 1171 ) that supplies a signal to the first display unit ( 11 ), the first line group ( 1171 ) passing through between the first substrate ( 111 ) and the second substrate ( 121 ); and a second line group ( 1271 ) that supplies a signal to the second display unit ( 12 ), the second line group ( 1271 ) passing through between the first substrate ( 111 ) and the second substrate ( 121 ). The first display unit ( 11 ) includes a mounting area to which the first line group ( 1171 ) is connected, in a part that is opposed to the second display unit ( 12 ), and the second display unit ( 12 ) includes a mounting area to which the second line group ( 1271 ) is connected, in a part that is opposed to the first display unit ( 11 ).

First claim
