Claim Text:
1. A liquid crystal display device comprising: a first substrate; a second substrate which faces the first substrate; a liquid crystal layer which is interposed between the first and second substrates; and a columnar spacer which defines the thickness of the liquid crystal layer, the liquid crystal display device having a plurality of color display pixels which are arranged in columns and rows to form a matrix pattern, each of the plurality of color display pixels being defined by a plurality of pixels, which are first, second and third pixels that represent mutually different colors, wherein the first substrate includes a pixel electrode which is provided for an associated one of the plurality of pixels, a thin-film transistor which is electrically connected to the pixel electrode, and an interlayer insulating layer which covers the thin-film transistor, the second substrate includes a counter electrode which faces the pixel electrode, first, second and third color filters which transmit light rays in mutually different colors, and an opaque layer, the thin-film transistor includes a gate electrode, a source electrode, and a drain electrode, the interlayer insulating layer has a contact hole to connect the pixel electrode electrically to the drain electrode of the thin-film transistor, the first, second and third color filters are arranged in a delta arrangement, each of the plurality of pixels has a substantially polygonal shape with n vertices (where n is an integer which is equal to or greater than eight) or a substantially circular shape, the thin-film transistor and the columnar spacer which are associated with each of the plurality of pixels are arranged in a first tricolor boundary region which is defined between the first, second and third pixels, the contact hole associated with each of the plurality of pixels is arranged in a second tricolor boundary region which is also defined between the first, second and third pixels but which is different from the first tricolor boundary region, and when the first and second tricolor boundary regions are associated with an arbitrary one of the plurality of pixels, two of the first, second and third pixels that define the first tricolor boundary region are the same as two of the first, second and third pixels that define the second tricolor boundary region, and the other of the first, second and third pixels that define the first tricolor boundary region is arranged at a different location from the other of the first, second and third pixels that define the second tricolor boundary region.
