  • Publication number: 20080108157
    Abstract: There is provided a method for manufacturing a display device. The method includes the steps of: forming a bottom electrode for supplying a first charge, in individual pixels on a substrate; forming a pattern of a first light-emitting layer having a first-charge transport property above the bottom electrode in part of the pixels; subjecting the substrate having the first light-emitting layer formed thereon to heat treatment; forming a pattern of a second light-emitting layer having a second-charge transport property on the heat-treated surface above the bottom electrode in the other pixels; and forming a top electrode for supplying a second charge so that the first light-emitting layer and the second light-emitting layer are sandwiched between the bottom electrode and the top electrode.

  • Patent number: 6993214
    Abstract: The invention provides a light emitting device which can prevent irregular color by reducing film thickness distribution and a display unit using it. A first electrode, an organic layer including a light emitting layer, a second electrode including a semi-transparent electrode are sequentially layered on a driving substrate. The light emitting layer has a red light emitting layer, a green light emitting layer, and a blue light emitting layer. The light emitting layer is formed by transferring a raw solution by every color, and then removing the solvent. An optical distance between a first end of the first electrode and a second end of the second electrode satisfies (2L)/?+?/(2?)=m. ? represents a peak wavelength of a spectrum of a light desired to be extracted, ? represents a phase shift of reflected lights generated in the first end and the second end, and m represents an integer.
