Organic light emitting display panel and method of manufacturing the same
First Claim
1. An organic light emitting display panel comprising:
- a base substrate comprising first pixels configured to emit a light having a first wavelength and second pixels configured to emit a light having a second wavelength; and
a pixel definition layer disposed on the base substrate, the pixel definition layer comprising first and second openings, wherein the first opening corresponds to light emitting areas of n (n is a natural number equal to or greater than
2) first pixels among the first pixels, the second opening corresponds to light emitting areas of m (m is a natural number equal to or greater than 1 and smaller than n) second pixels among the second pixels, and an area of the light emitting area of each of the first pixels is smaller than an area of the light emitting area of each of the second pixels.

Abstract
An exemplary embodiment discloses an organic light emitting display panel including a base substrate comprising first pixels configured to emit a light having a first wavelength and second pixels configured to emit a light having a second wavelength and a pixel definition layer disposed on the base substrate. The pixel definition layer includes first and second openings. The first opening corresponds to light emitting areas of n (n is a natural number equal to or greater than 2) first pixels among the first pixels. The second opening corresponds to light emitting areas of m (m is a natural number equal to or greater than 1 and smaller than n) second pixels among the second pixels. An area of the light emitting area of each of the first pixels is smaller than an area of the light emitting area of each of the second pixels.

14. A method of manufacturing an organic light emitting display panel, comprising:
-
disposing an anode layer comprising first anodes and second anodes, each second anode having an area greater than each of the first anodes on a base substrate; disposing a pixel definition layer comprising a first opening exposing n (n is a natural number equal to or greater than
2) first anodes of the first anodes and a second opening exposing m (m is a natural number equal to or greater than 1 and smaller than n) second anodes of the second anodes;disposing a liquefied material to areas corresponding to the first and second openings to form hole transport regions on the n first anodes and the m second anodes; disposing a first liquefied organic material to an area corresponding to the first opening to form a first light emitting layer and a second liquefied organic material to an area corresponding to the second opening to form a second light emitting layer; disposing electron transport regions on the first and second light emitting layers; and disposing a cathode on the electron transport regions. - View Dependent Claims (15, 16, 17, 18, 19, 20)
