Abstract
To provide a display device for improving light extraction efficiency.SOLUTION: There is provided a display device that includes a board, an insulation layer that is positioned on the board and includes at least one recessed section having a center point while at least one recessed section includes a flat section and a sloped section surrounding the flat section, and a bank layer that is positioned on one sub-pixel on the insulation layer within at least one recessed section and on the insulation layer, and includes an opening area corresponding to the sub-pixel while the opening area includes a center point, the opening area is surrounded by the sloped section, and the center point of at least one recessed section deviates from the center point of the opening area of the bank layer so as to improve light extraction efficiency, and hence achieve low-power drive with high-luminance characteristics.SELECTED DRAWING: Figure 9a
