PROBLEM TO BE SOLVED: To improve luminous efficiency and color purity of a top emission blue light emitting OLED, decrease a driving voltage thereof, and thereby improve the full-color display balance and the total performance of a product.SOLUTION: The present invention provides a top emission blue light emitting OLED and a method for manufacturing the OLED. The top emission blue light emitting OLED includes: a reflective electrode as an anode; a hole injection layer formed on the reflective electrode; a luminous layer formed on the hole injection layer; an electron transport layer formed on the luminous layer; and a transparent electrode formed on the electron transport layer, as a cathode. The hole injection layer includes a metal phthalocyanine compound. |
