TFT array panel and a method for their preparation

TFT array panel, the insulating substrate, insulated from the gate wire is formed on the substrate including a gate line and a gate electrode, and the semiconductor pattern formed on the gate electrode, formed on the semiconductor pattern data line, a source electrode and a drain electrode through the data line and the first sub protection film and the second contact hole formed on the protective film and the protective film laminated in the sub-protective film on the data line including the pixel electrode includes a connection to the drain electrode. Here, the second sub-protecting film may be less dense than the first sub-protecting film. A liquid crystal display device, the photosensitive film, reflow (reflow), the host leaf (strip)
