1. A display unit comprising a display section having a plurality of organic EL devices with light emitting color different from each other and a plurality of pixel circuits that are singly provided for every said organic EL device for every pixel, wherein the each pixel circuit has a first transistor for writing a video signal, a second transistor for driving the organic EL device based on the video signal written by the first transistor, and a retentive capacity, andthe first transistor and the second transistor of a second organic EL device which is adjacent to a first organic EL device are arranged farther from the first organic EL device than the retentive capacity of the second organic EL device,the first transistor and the second transistor of a third organic EL device which is adjacent to the second organic EL device are arranged farther from the second organic EL device than the retentive capacity of the third organic EL device,the first transistor and the second transistor of the first organic EL device which is adjacent to the second organic EL device are arranged farther from the second organic EL device than the retentive capacity of the first organic EL device,the first organic EL device, the second organic EL device and the third organic EL device are formed in a line next to each other, wherein the second organic EL device is located between the first organic EL device and the third organic EL device;

  • andthe first transistor has a drain that is connected to a signal line through lead wiring which does not overlap the aperture of the EL device, and a source that is connected to a gate of the second transistor and an end of the retentive capacity at a point overlapped by the aperture of the EL device,wherein the gate of the second transistor is entirely overlapped by the aperture of the EL device.
