PIXEL AND DISPLAY DEVICE COMPRISING THE SAME

A pixel includes first (SPX1), second (SPX2), and third (SPX3) sub-pixels each including an emission area (EMA) and a non-emission area (NEA). Each of the first, second, and third sub-includes a pixel circuit layer; a first electrode (EL1) on the pixel circuit layer; a pixel defining layer (PDL) on...

More Information
Summary:A pixel includes first (SPX1), second (SPX2), and third (SPX3) sub-pixels each including an emission area (EMA) and a non-emission area (NEA). Each of the first, second, and third sub-includes a pixel circuit layer; a first electrode (EL1) on the pixel circuit layer; a pixel defining layer (PDL) on the first electrode and including an opening to expose an area of the first electrode; an emission layer (EML) on the pixel defining layer; a second electrode(EL2) on the emission layer; a thin film encapsulation layer (TFE) over the second electrode; a color filter (CFL) on the thin film encapsulation layer; and an overcoat layer (OC) over the color filter. The overcoat layer has a refractive index greater than a refractive index of the color filter. A color filter of the second sub-pixel overlaps a color filter of each of the first and third sub-pixels in the non-emission area.
