Display device and manufacturing method thereof

The invention relates to a display device and a manufacturing method thereof. Disclosed is a display device in which a power connection line contact is provided on a structure provided in each sub-pixel and is thus electrically connected to a cathode electrode layer such that power is supplied to each of a plurality of sub-pixels through the power connection line electrically connected to a power line. 本公开涉及显示装置及其制造方法。公开了一种显示装置，其中，电力连接线接触设置在设置于每一子像素中的结构上，并因而电连接至阴极电极层，使得电力被通过电连接至电力线的电力连接线提供给多个子像素中的每者。
