  • Patent number: 7572656
    Abstract: A method for fabricating a device is disclosed. The method includes providing a substrate; forming a thin film on the substrate; forming a photoresistable layer on the thin film; irradiating light onto the photoresistable layer through a photo mask having a transmissive region, a semi-transmissive region, a diffractive region and an interceptive region, and developing the photoresistable layer to form a photoresist pattern having at least three different thicknesses. With the above-described process, a liquid crystal display device (LCD), for example, can be manufactured using three photo masks.

  • Patent number: 7280168
    Abstract: A liquid crystal display device and a fabricating method thereof that are capable of preventing breakage of a pixel electrode. In the device, the protective layer pattern is provided at the overlapping area between the storage electrode and the pixel electrode to separate the storage electrode and the pixel electrode. Accordingly, the protective layer pattern is formed at the storage capacitor area to improve step coverage of a transparent conductive material.
