DISPLAY AND METHOD FOR MANUFACTURING DISPLAY

摘要

A display includes a pixel array part with pixels that each have at least one transistor whose conduction state is controlled by a drive signal input to a control terminal, and a scanner including a plurality of buffers that are formed of transistors. The buffers correspond to a pixel arrangement and output a drive signal to the control terminals of the transistors of the pixels. The transistors of the pixels and the transistors of the buffers are formed through irradiation with laser light that is moved for scanning in a predetermined direction and has a predetermined wavelength. The transistors in the buffers are formed in such a way that the channel length direction of the transistors is set parallel to the scan direction of the laser light.

1. A display comprising:
a pixel array part that includes a plurality of pixel circuits that are arranged in a matrix form in columns and rows and a plurality of light emitting elements, each of the plurality of pixel circuits having a pixel transistor;wherein
the respective pixel transistors of the plurality of pixel circuits are formed through irradiation with laser light and have channel lengths extending in a first direction, the plurality of pixel circuits are arranged in stripes that extend in the column direction, and a crystal structure of the pixel transistor of each of the plurality of pixel circuits is such that crystal grain size considered along a center line of the pixel transistor in a second direction is more uniform than crystal grain size considered along a center line of the pixel transistor in the first direction, where the second direction is perpendicular to the first direction.
