摘要： A display device, having relatively high side visibility and transmittance, includes a first substrate having a plurality of red, green, and blue pixel regions; a lower electrode disposed on the red, green, and blue pixel regions; and an upper electrode disposed on the red, green, and blue pixel regions. The upper electrode is insulated from the lower electrode, and includes a plurality of upper branch electrodes disposed on the lower electrode. A width and height of the upper branch electrode in at least one of the red, green, and blue pixel regions are respectively different from a width and a height of the upper branch electrode in another of the red, green and blue pixel regions.
