Organic electroluminescent display device
View Patent ↗The present invention overcomes image defects such as the brightness inclination or smears by reducing the line resistance of a power source bus line which supplies electricity to organic EL elements. A plurality of pixels which are arranged in a matrix array is connected to power source lines, and the plurality of power source lines are connected to a power source bus line. Both ends of the power source bus line are connected to a power source part via a FPC. By supplying electricity to both ends of the power source bus line from the power source part, the line resistance of the power source bus line can be reduced.
1. An organic EL display comprising:
a substrate having a display region;
a scanning line drive circuit arranged on a second side adjacent to the first side of the substrate and a flexible printed circuit connected to the substrate, wherein:
the display region has a plurality of pixels arranged in a matrix array, power source lines electrically connected to the plurality of pixels, data lines supplying data signals to the plurality of pixels, and scanning lines supplying scanning signals to the plurality of pixels,
a power source bus line is arranged across the data lines in plan view and arranged between the display region and the flexible printed circuit, and
electricity is supplied from a power source via the flexible printed circuit to a plurality of electricity supply portions of the power source bus line, and
a cathode contact is connected to cathode of the plurality of pixels, and the cathode contact is connected to the flexible printed circuit through between edge of the substrate and the power source bus line.
2. An organic EL display according to claim 1 , wherein the power source lines are connected at opposite side of display region.
3. An organic EL display according to claim 1 , the display region is sealed by a sealing substrate ( 13 ) and a sealing material.
