This invention provides a polycyclic aromatic compound, an organic electroluminescent element, a display device, a lighting device, a wavelength conversion material, an organic photodiode, and a solar cell material that can be effectively used as a material for organic EL elements and other organic devices. The polycyclic aromatic compound represented by formula (I) enables the manufacture of high-efficiency and long-life organic EL elements; rings A, B, D, E, and F are aryl or heteroaryl rings, at least one of which has a cyano group as a substituent, and Z... 0 Let C(-H) = , Y be B, X 1 ~X 4 For >N-R NX >O or >S, R NX For unsubstituted aryl, where X 1 and X 2 It is R NX The N-R of the basis represented by equation (Ar) NX , or X 1 and X 3 or X 2 and X 4 They are R NX N-R of mesitylene NX G represents a substituted or unsubstituted aryl group or a substituted or unsubstituted alkyl group, etc.

The present application relates to a polycyclic aromatic compound represented by formula (1) or a multimer of a polycyclic aromatic compound having a plurality of structures represented by formula (1) below, a compound, a crosslinked body, a material, and a device containing the same. The compound or the multimer of the present application is effective as a material for organic devices such as an organic EL element.

An organic device includes a reflective film arranged on a substrate, a plurality of lower electrodes arranged above the reflective film, an organic function film configured to cover the plurality of lower electrodes, and an upper electrode arranged on the organic function film. A potential difference between the upper electrode and the reflective film is lower than a threshold voltage at which the organic function film operates.

To provide a mask which can make uniform the thickness of a vapor deposition material attaching to a substrate.SOLUTION: A mask 20 includes a first layer including at least one first opening, and a metal layer 40 including a plurality of second openings 41 overlapped with the first opening in a plane view. The metal layer 40 includes an effective region formed with a plurality of second openings 41, and a peripheral region surrounding the effective region. The peripheral region has a section 48A surrounded by a recess or a lost part 43.SELECTED DRAWING: Figure 4
