PURPOSE: A light emitting polymer as pigment for display is provided to achieve excellent film processability, applicability in the field of organic material display, and workability of electro-luminescence display (ELD) in a low operating voltage. CONSTITUTION: The electro-luminescence display is comprised of a substrate(11); a front side electrode layer(12) on the substrate; groove injecting layer(13) on the electrode layer; light emitting layer(14) and electron injecting layer(15); and a rear side electrode layer(16) on the electron injecting layer. Also, at least one of the groove injecting layer, light emitting layer or electron injecting layer includes a silicon-containing repeating unit between conjugated double bond, the repeating unit comprising of formula 1 (wherein R1 and R2 are phenyl; R4 is hydrogen, unsubstituted or hydrocarbon substituted C1-C24 alkyl, unsubstituted or hydrocarbon substituted aromatic ring; and n is an integer from 1 to 100).
