Abstract

The present invention relates to a display and its manufacturing method, device and transfer printing method, wherein a display comprises: a first light-emitting layer to be transferred to a first region on a substrate; a second light-emitting layer to be transferred to a substrate; the second light emitting layer in the region; and a height difference forming member forming a first height difference between the first region and the second region, when the first light emitting layer is transferred to the first region, the first height difference inhibits the first Attachment of the light-emitting layer to the second region.

Description

technical field [0001] The present disclosure relates to a display and a method of manufacturing the display, to an electronic device, a device, and a transfer printing method. [0002] The present invention also relates to an organic electroluminescence (EL) device that emits light by utilizing the organic EL phenomenon, a method of manufacturing the organic EL device, and electronic equipment. Background technique [0003] Recently, it has been proposed to form a light emitting layer (organic layer) of an organic EL display by a printing method. The advantage of the printing method is that compared with the vacuum evaporation method, its process cost is low and it is easy to form a larger device. [0004] The printing method is roughly classified into a non-contact type and a contact type. An inkjet method and a nozzle printing method are known as examples of non-contact type methods. The advantages of these methods are the ease of forming larger devices and the high ef...
