Patent abstract
To provide a liquid crystal display device having high visibility and high image quality by relieving color phase irregularity. A light-shielding layer is selectively provided so as to overlap with a contact hole for electrical connection to a source region or a drain region of a thin film transistor. Alternatively, by providing an opening portion of a colored layer (color filter) with an opening so as to overlap with a contact hole, uneven alignment of liquid crystal molecules does not influence display, and a liquid crystal display having high image quality can be provided.
