Abstract:
A photo mask includes a transparent substrate and a mask pattern. The mask pattern is disposed on the transparent substrate. The mask pattern includes a blocking portion for blocking light and a transmitting portion for transmitting the light. The transmitting portion is adjacent to the blocking portion. The blocking portion includes a first blocking layer, a photo guide layer and a second blocking layer. The first blocking layer is disposed on the transparent substrate. The first blocking layer transmits a portion of the light. The first blocking layer includes a plurality of blocking patterns including a first blocking material. The photo guide layer is disposed on the first blocking layer. The photoguide layer guides the transmitted portion of the light to a side surface of the photoguide layer. The second blocking layer reflects the transmitted portion of the light.

A photoresist composition may include a novolac resin, a diazide-based photosensitive compound, a surfactant represented by Chemical Formula 1 below, and a solvent. R1 and R2 may denote a hydrogen atom or an alkyl group, x may be 10-50, and y may be 10-50.
Abstract:
In a method for manufacturing a display substrate, a thin film transistor is formed on a base substrate. The thin film transistor includes a gate electrode, an active pattern, a source electrode and a drain electrode. A first passivation layer is formed to cover the thin film transistor. A second passivation layer is formed on the first passivation layer. A photoresist pattern is formed to partially expose the second passivation layer. The first passivation layer and the second passivation layer are partially removed to form a contact hole exposing the drain electrode. A pixel electrode layer is formed on the second passivation layer, the drain electrode and the photoresist pattern. A portion of the pixel electrode layer and the second photoresist pattern are removed to form a pixel electrode. The portion of the pixel electrode layer is disposed on a top surface and a sidewall of the photoresist pattern.
