The present invention provides an organic light emitting device array which reduces the change of white balance even if an observation angle is changed. In an organic light emitting device array comprising a plurality of organic light emitting devices which emit lights of different colors, an optical path difference is set such that signs of gradients at an optical path difference of 2 L of interferograms for all the plurality of organic light emitting devices are identical to each other.

Organic light-emitting device array and display

In a display apparatus, a plurality of pixels including light emitting elements emitting colors of R, G and B, is arranged on a single surface. To each pixel, corresponding R image signal wiring, G image signal wiring, and B image signal wiring, are connected. Wirings are arranged so that the resistance or the capacitance of each image signal wiring differs every color of corresponding pixels, and by this, the rise times of the signal for R, G and B will be substantially equal to each other. The resistance value is changed by adjusting the width, the thickness, or the specific resistance of the material of the image signal wiring, or the capacitance is changed by adjusting the thickness of the insulator or the relative dielectric constant of the material while sandwiching an insulator between the image signal wiring and a scanning wiring at the intersection of them.

Display apparatus

Provided is a display apparatus capable of reducing external light reflection to reduce an amount of glare of the outside, in which a translucent protection member is provided to cover an observation surface side of a display member including an organic EL light-emitting portion, in order to protect the display member. The display apparatus includes the display member with an organic EL light-emitting portion having a pair of electrodes and an organic compound layer provided between the pair of electrodes; and a casing for housing the display member, wherein a protection member is provided in the casing with a gap from the display member, and wherein a phase member and a polarizing member are formed on the protection member such that the polarizing member is located closer to a light extraction side than the phase member.
