Abstract: An organic electroluminescent device, a method for preparing an organic electroluminescent device, and a display panel are disclosed. The organic electroluminescent device comprises a conductive layer formed by transparent magnetic conductive particles which are mixed in the sealing layer and stacked on a surface of the first transparent electrode layer. The conductive layer increases the conductive performance while not increasing the thickness of the first transparent electrode layer, thereby avoiding decrease of the light transmittance caused by increase of the thickness of the first transparent electrode layer, and avoiding the problem of voltage drop due to poor conductivity of the first transparent electrode layer, so as to improve the display effect and use stability of the organic electroluminescent device.

Abstract: An organic light emitting display substrate comprises a substrate, a first pixel defining layer provided on the substrate and a second pixel defining layer provided on the first pixel defining layer. The first pixel defining layer includes a plurality of first openings, and the second pixel defining layer includes a plurality of second openings in one-to-one correspondence with the plurality of first openings. An edge of each of the plurality of second openings extends outwards beyond an edge of the corresponding first opening so as to expose a portion of the first pixel defining layer, and a difference in length between each of the plurality of second openings and the corresponding first opening is greater than a difference in width between the second opening and the corresponding first opening.
