A display device includes: a glass substrate including a driver circuit and a plurality of connection terminals that is connected to the driver circuit and is arranged in an array, and an elongated FPC, which has a plurality of panel connection terminals that correspond to the connection terminals and which is mounted on the glass substrate, wherein the FPC has a coverlay. The FPC has a chamfered-area end gap between an end portion of the coverlay facing an end face of the glass substrate and a chamfered-area end portion of the glass substrate in a mounted state, wherein the chamfered-area end gap is covered with an insulating resin, and wherein the chamfered-area end gap at a center portion of the FPC is narrower than the chamfered-area end gap at both end portions of the FPC.
