Patent ID: 6842164

Claim:
A display device comprising: a substrate having a plurality of gate lines extended in a first direction, a plurality of drain lines extended in a second direction transverse to the first direction, and a plurality of pixels having switching elements respectively and being arranged along the first direction and the second direction; a plurality of drain driver circuits being provided along the first direction on a first periphery of the substrate and each applying gray scale voltage signals on the basis of display data signals acquired thereby to the switching elements of a group of the plurality of pixels corresponding thereto through a group of the plurality of drain lines connected thereto, a plurality of gate driver circuits being provided along the second direction on a second periphery of the substrate adjacent to the first periphery of the substrate and controlling the switching elements of the plurality of pixels through the plurality of gate lines respectively, first data lines formed on the first periphery of the substrate, each of which connects a respective pair of the plurality of drain driver circuits adjacent to each other to transfer the display data signals from a first one of the plurality of drain driver circuits at one end of the first periphery of the substrate to a last one of the plurality of drain driver circuits at another end of the first periphery of the substrate sequentially in serial; second data lines formed on the second periphery of the substrate and transferring scanning clock signals between respective pairs of the plurality of gate driver circuits sequentially in serial; and a flexible printed substrate comprising a drain driver power supply line section and an interface wiring section, wherein the drain driver power supply line section has a drain driver power supply line formed thereon to be extended along the first periphery of the substrate and connected to each of the plurality of drain driver circuits, and the interface wiring section is arranged at the one end of the first periphery of the substrate, and has an extension of the drain driver power supply line, a first data connecting line connected to one of the first data lines, and a first data connecting line connected to one of the second data lines, each formed thereon.
