An exposure apparatus comprises a first detector detecting substrate-side marks via an original-side mark and a projection optical system; second detectors arranged in a larger number than the first detector and detecting the substrate-side marks not via the projection optical system; a reference plate having reference marks; and a control unit configured to obtain a first detection result of the plurality of reference marks by the second detectors, obtain first information relating to a first distance between the plurality of second detectors based on the first detection result, obtain a second detection result of the identical substrate-side mark by the first detector and the second detectors, obtain second information relating to a second distance between the first detector and the second detectors based on the second detection result, and control the alignment of the original and the substrate based on the first information and the second information.

Exposure apparatus and method for manufacturing article

A method for manufacturing an organic EL display device is provided in which an organic compound layer is formed by vapor deposition after a layer used for patterning the organic compound layer has been formed, so that the organic compound layer is formed without being affected by the surface tension of the sides of the layer for the patterning.

Light is prevented from being emitted from a region that overlaps a contract hole in a structure in which light emitting devices are stacked. A stacked organic electro-luminescent display apparatus includes a contact hole that electrically connects a first electrode or a second electrode to a driving circuit. The first or second electrode and a second organic compound layer are provided in the contact hole, and the second organic compound layer existing in the contact hole does not emit light.

A method of manufacturing an organic electroluminescent device includes a step of forming a masking layer and an intermediate layer on a first organic compound layer such that the masking layer and the intermediate layer have a predetermined pattern, a step of patterning the first organic compound layer using the masking layer and the intermediate layer, a step of forming a second organic compound layer, and a step of removing the intermediate layer and the second organic compound layer formed thereon in such a manner that the intermediate layer is contacted with a dissolving liquid for dissolving the intermediate layer. In the method, the first and second organic compound layers are protected by covering the first and second organic compound layers with a sacrificial layer until the patterning of the first and second organic compound layers is completed.

A method for producing an organic light-emitting device is provided for an organic light-emitting device having a substrate provided with external connection terminals, organic light-emitting elements provided on the substrate, and a protective film that covers the organic light-emitting elements. The method includes, sequentially, providing a protective film removal layer on the external connection terminals, forming the protective film on the substrate, dividing the substrate on which the protective film has been formed, and cleaning the substrate with water, an aqueous solution, or a solvent. The protective film removal layer and the protective film are removed from the external connection terminals as a result of cleaning the substrate.

Display apparatuses are enhanced in reliability in such a manner that external moisture is prevented from penetrating display regions and planarization layers are prevented from being stripped off. In particular, in a display apparatus including a display region containing organic light-emitting devices arranged on a circuit substrate, a bank-separating region separating a bank is provided in a planarization layer-separating region separating a planarization layer, an end portion of the planarization layer is covered with the bank, an end portion of an organic protective layer extending over the display region is spaced from a portion of the planarization layer that is located outside the bank-separating region and a portion of the bank that is located outside the bank-separating region, and the inorganic protective layer and an end portion of the bank that is disposed in the display region are covered with an inorganic protective layer.

An organic EL display apparatus is sealed with a protective film composed of a resin protective film and an inorganic protective film. In the organic EL display apparatus, a planarizing film has a dividing region which divides the planarizing film into a region where organic EL elements are arranged and a peripheral region thereof. An end of the resin protective film is located in the dividing region or in the region where the organic EL elements are arranged, away from the planarizing film in the peripheral region. The inorganic protective film covers the end of the resin protective film and further extends to the dividing region.
