Abstract:
1. An organic thin film transistor including a substrate, a gate electrode, a gate insulating layer, an organic semiconductor layer, a source electrode, and a drain electrode, the organic thin film transistor comprising: a fluorine-based polymer thin film formed between the gate insulating layer and the organic semiconductor layer, wherein the fluorine-based polymer thin film is formed of a polymer having a number ratio of carbon atoms to fluorine atoms from about 5:1 to about 30:1 and containing at least one repeating unit selected from the group consisting of repeating units represented by Formula 1 and repeating units represented by Formula 2 below: wherein X is a hydrogen atom, a C wherein R R and R (where X contains at least one fluorine atom, and X is independently H, F, CF k is an integer between 1 and 3, provided that when k is 2 or greater, each R l is an integer between 0 and 5, provided that when l is 2 or greater, each R
