Flexible display device
A flexible display device including a substrate having an active region in which an input image is implemented and a bezel region outside the active region; a signal line (or an electrode) extending from the bezel region and transmitting a signal (or a voltage) to the active region; and a first bypass line provided above or below the signal line with one or more insulating layers interposed therebetween in the bezel region, wherein the first bypass line is connected to the signal line via a first bypass contact hole penetrating through the one or more insulating layers and receives the same signal as that of the signal line, and wherein the first bypass contact hole is provided as at least two bypass contact holes.
1. A flexible display device, comprising:
a substrate having an active region in which an input image is implemented and a bezel region outside the active region;
a signal line or an electrode extending from the bezel region and transmitting a signal or a voltage to the active region;
a first bypass line provided above or below the signal line or the electrode with one or more first insulating layers interposed therebetween in the bezel region, wherein the first bypass line is connected to the signal line or the electrode via at least two first bypass contact holes penetrating through the one or more first insulating layers and receives the same signal or the same voltage as that of the signal line or the electrode; and
at least one second bypass line provided above or below the first bypass line with one or more second insulating layers interposed therebetween in the bezel region, wherein the second bypass line is connected to the first bypass line via at least two second bypass contact holes penetrating through the one or more second insulating layers and receives the same signal or the same voltage as that of the signal line or the electrode and the first bypass line.
2. The flexible display device of claim 1 , wherein at least a third first bypass contact hole is provided, the first bypass line being connected to the signal line or the electrode via the third first bypass contact hole such that the first bypass line provides at least first and second bypass transmission paths.
3. The flexible display device of claim 1 , wherein at least a third second bypass contact hole is provided, and the second bypass line being connected to the first bypass line via the third second bypass contact hole such that the second bypass line provides at least third and fourth bypass transmission paths.
4. The flexible display device of claim 1 , further comprising:
a data driving circuit supplying a data voltage to the active region;
a gate driving circuit supplying a gate signal to the active region; and
a power generating unit generating a source voltage,
wherein the signal line includes one or more of
a data line receiving the data voltage;
a gate line receiving the gate signal; and
a power line receiving the source voltage.
5. The flexible display device of claim 1 , further comprising:
data lines, gate lines, and source voltage lines disposed to cross each other to divide pixels in the active region; and
at least one thin film transistor (TFT) provided in each of the pixels,
wherein the signal line comprises one or more of
a data line to which a data voltage is applied;
a gate line to which a gate signal is applied; and
a power line to which a source voltage is applied.
6. The flexible display device of claim 4 ,
wherein the source voltage is any one of a high potential source voltage, a low potential source voltage, and a reference voltage.
7. The flexible display device of claim 5 ,
wherein the source voltage is any one of a high potential source voltage, a low potential source voltage, and a reference voltage.
