LIGHT-EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light-emitting device with high uniformity of image quality.SOLUTION: A printed wiring board (a second substrate) 107 is provided to face a substrate (a first substrate) 101 provided with a light-emitting element 102. PWB side wiring (a second wiring group) 110 on the printed wiring board 107 are electrically connected to element side wiring (a first wiring group) 103 and 104 by anisotropic conductive films 105a and 105b. The use of a low resistance copper foil for the PWB side wiring 110 can reduce the voltage drop and signal delay in the element side wiring 103 and 104, and can improve the uniformity of image quality and the operation speed of a driver circuit portion.
