A display device with an integrated touch screen panel is disclosed. In one aspect, the display device includes an upper substrate and a lower substrate each including a display region and a non-display region. A sealing member is formed between the non-display regions of the upper and lower substrates and the sealing member includes a first region and a second region, wherein the second region is located adjacent to the corners of the substrates. An electrode is formed over substantially the entire display region of the lower substrate. A power line is formed in the non-display region of the lower substrate and a first connection electrode is formed electrically connecting the power line to an end portion of the electrode. Each of the power line, the end portion of the electrode, and the first connection electrode at least partially overlaps the first region and does not overlap the second region.
