Claim:
1. A display device, comprising: a first substrate including a plurality of pixel electrodes, a plurality of active elements and a plurality of wiring lines that connect to the plurality of active elements, wherein the plurality of active elements are thin film transistors disposed on the first substrate; a second substrate including a common electrode, wherein the common electrode is disposed on the second substrate opposite to the plurality of pixel electrodes disposed on the first substrate; a display region in which the plurality of pixel electrodes and the plurality of active elements are aligned in a plan-view of the first substrate; a seal region positioned around the display region in the plan-view of the first substrate; and a seal member in the seal region and disposed between the first substrate and the second substrate so as to the common electrode faces to the plurality of pixel electrodes, and the seal member is formed continuously around the entire display region without the use of a plug, wherein the first substrate includes a protruding region which protrudes over the second substrate in the plan-view of the first substrate and a plurality of conductive portions, the plurality of conductive portions being a plurality of dot conductive points, the seal region forms a rectangular closed-shape so as to surround the display region, and has a first side, a second side, a third side and a fourth side, the first side is positioned between the display region and the protruding region, and opposed to the third side, and the second side is opposed to the fourth side, and the seal member includes a first seal portion and a second seal portion, the first seal portion and the second seal portion form the rectangular closed-shape between the first substrate and the second substrate and do not protrude from the second substrate in a plan-view of the first substrate, wherein the first seal portion is disposed at least on the first side and the second seal portion is disposed at least on the third side, the first seal portion and the second seal portion are connected in a first junction portion positioned on the second side, and the first seal portion and the second seal portion are connected in a second junction portion positioned on the fourth side, wherein the second seal portion includes a plurality of conductive particles and the plurality of dot conductive points are disposed at least on the third side and all of the plurality of dot conductive points are electrically connected to the common electrode, and the plurality of wiring lines extend onto the protruding region across the seal member without connecting to the plurality of dot conductive points.
