PURPOSE: A polymer including a thiophene condensed ring unit, and a polymer light emitting diode using thereof are provided to apply the polymer with an improved electron transport performance to various uses. CONSTITUTION: A polymer has a number average molecular weight of 1,000~a billion and includes a repeating unit marked as chemical formula 2a~2e. In the chemical formulas, X is S or O. R1~R10 are selected from the group consisting of an alkyl group, an alkoxy group, an alkylthio group, an aryl group, an aryloxy group, an arylalkyl group, an arylalkoxy group, and others, respectively. A and B are integers selected from 0~3, respectively. C, D, E, and F are integers selected from 0~5, respectively. G, H, I and J are integers selected from 0~7, respectively.
