Embodiment approach

[0279] According to still another exemplary embodiment of the present disclosure, the capacitor electrode 1125 may be made of the semiconductor layer 416 having conductive properties, and as Figure 11 Connected to gate 420 as shown. But the present disclosure is not limited thereto, and the capacitor electrode 1125 may be configured as the capacitor electrode 425 of another exemplary embodiment of the present disclosure.

[0280] According to the above configuration, the light-shielding capacitor electrode 1126 can generate double capacitance. Accordingly, capacitance can be increased in a relatively small area. As a result, it is beneficial to realize a high-resolution top emission type electroluminescent display device and if the stacked structure and thickness of the light-shielding capacitor electrode 1126 and the source electrode 424 are the same as those of the light-shielding capacitor electrode 1126, and the source electrode 424 can be manufactured by the same manufa...

Abstract

An electroluminescence display apparatus comprising: a plurality of sub-pixel circuit units arranged in a matrix form; at least one gate line disposed between the plurality of sub-pixel circuit unitsand extending along a first direction; a plurality of first data line groups and a plurality of second data line groups alternatively disposed between the plurality of sub-pixels circuit units and extending along a second direction; a plurality of common lines disposed within the first or the second data line groups and extending along the second direction; and a plurality of anode lines disposedwithin the first or the second data line groups and extending along the second direction.

Description

technical field [0001] The present disclosure relates to a top emission type electroluminescence display device capable of improving electroluminescence by reducing the degree of deviation in potential between an anode and a cathode according to the position of each pixel within a pixel region of the electroluminescence display device Brightness uniformity of the display device. The electroluminescent display device of the present disclosure is also capable of improving the uniformity of potential when the electroluminescent display device is enlarged. Background technique [0002] An organic light-emitting display device, which is a self-luminous display device, does not require a separate or additional light source like a liquid crystal display device, and thus can be reduced in weight and thickness. In addition, the organic light emitting display device is advantageous not only in low power consumption due to its low driving voltage, but also in fast response speed, wide...
