Display device, including: substrates, color filters having first and second color filters, drain and gate signal lines (of light blocking material), wherein, an overlapping portion adjacent the first and second color filter overlap, is formed on a region with one of the drain or gate signal lines, a first color filter edge is a first taper and a second color filter edge is a second taper, in the overlapping portion, the first taper is closer to the drain or gate signal line than the second taper in the overlapping portion, the first taper angle is 45&#xb0; or more and 90&#xb0; or less corresponding to a surface of the drain or gate signal line, the second taper angle is 45&#xb0; or more and 90&#xb0; or less corresponding to a surface of the first taper and, the first taper angle is larger than the second taper angle.

Liquid crystal display device and manufacturing method for same

A liquid crystal display device with a higher aperture ratio is provided. According to one embodiment of the present invention, second color filters are formed so as to overlap with first color filters when adjacent color filters having different colors are formed on the TFT substrate side, so that the angle of the first tapers where said first color filters overlap and the angle of the second tapers where said second color filters overlap are set to 45&#xb0; or more and 90&#xb0; or less.

The present invention provides a liquid crystal display device including a first substrate and a second substrate that are arranged to face each other while sandwiching liquid crystal, wherein: a first electrode and plural second electrodes are formed at a pixel area on the first substrate on the liquid crystal side; an alignment layer is provided which includes a first alignment layer formed on the first substrate on the liquid crystal side to cover the second electrodes and a second alignment layer formed on the first alignment layer on the liquid crystal side; the resistance of the second alignment layer is lower than that of the first alignment layer; and the transmittance of the second alignment layer is lower than that of the first alignment layer.
