Embodiment Construction

[0113] [0034-SY1638] The following describes embodiments of the present invention with reference to the accompanying drawings. image 3 A schematic configuration diagram of the electroluminescent display panel 10 according to this embodiment is shown. On the display area (display portion) 14 on the panel substrate 12, several pixels are arranged in a matrix. On this display area (display portion) 14, gate lines 16 (GL) for sequentially outputting selection signals are formed in the horizontal scanning (row) direction, and data for outputting data signals are formed in the vertical scanning (column) direction. A line 18 (DL) and a power line 20 (PL) for supplying operating power (PVDD) to an organic electroluminescence element as a driven element.

[0114] [0035-SY1638] Each pixel is arranged in the area roughly defined by these lines, and each pixel has the following circuit configuration, that is, it has an organic electroluminescent element as a driven element; it is compos...

Abstract

The present invention provides an electroluminescence display device having a display portion in which pixels are arranged in a matrix in a display panel, which is characterized in that external connection terminals are arranged along one side of the display panel, and vertical scanning driving circuits are arranged On the side of the display panel opposite to the side where the external connection terminals are arranged. In addition, the wiring for the horizontal scanning driving circuit and the vertical scanning driving circuit can be provided only on the side on which the external connection terminal is provided, the opposite side, and the other three sides of the display panel, and the wiring for the remaining side can not be arranged. The wiring for the driving circuit can secure a space for the wiring of the driving current for supplying the electric power to the electroluminescence element on this side. Thereby, the width of the drive current common wiring can be ensured and the frame margin can be reduced.

Description

technical field [0001] [0001-SY1638] The present invention relates to wiring of a display panel using electroluminescent elements (hereinafter referred to as EL elements) as individual display elements arranged in a matrix. Background technique [0002] [0002-SY1638] As the display element of each pixel, there is known a display device using an electroluminescence element, especially an organic electroluminescence element using a current-driven light-emitting element. In addition, studies are actively being carried out on electroluminescence display devices, so-called active matrix display devices that include thin film transistors (TFT: Thin Film Transistor) in each pixel for driving each pixel individually. The organic electroluminescence element set in. [0003] [0003-SY1638] figure 1 An example of an equivalent circuit corresponding to one pixel of an active matrix display device is shown. Gate lines GL are arranged in the horizontal scanning direction (row direction)...
