Patent ID: 7253848

Claim:
An organic thin film transistor array substrate comprising: a substrate divided into a liquid crystal display (LCD) region and an organic thin film transistor (OTFT) region; a first dielectric layer formed on the substrate in the LCD region and having a first uneven portion; a second dielectric layer and an organic semiconducting layer formed on the substrate in the OTFT region; a gate, source, and drain formed in the OTFT region, wherein the source and drain are in contact with the organic semiconducting layer to form a channel between the source and drain; an alignment film between the second dielectric layer and the organic semiconducting layer, such that the organic semiconducting layer aligns according to the alignment of the alignment film, wherein the organic semiconducting layer is formed directly above and in physical contact with the alignment film; and a pixel electrode formed on the first uneven portion of the first dielectric layer in the LCD region.
