Abstract: There is achieved a liquid crystal display device having a smaller picture frame region and a seal part of improved reliability. A liquid crystal display device includes a TFT substrate having a display region and a terminal region and formed with an organic passivation film, a counter substrate attached to the TFT substrate through a seal part, and a liquid crystal contained inside the seal part. A hole is formed at a predetermined pitch on the organic passivation film of the TFT substrate corresponding to the seal part when viewed on a plane. When the hole is viewed on a plane, a shortest distance from the hole to the hole is four micrometers or greater and 12 micrometers or less at a height of h1=0.9×h2 from a bottom face of the hole, where a depth of the hole is defined as h2.

Abstract: Red pixels (R), blue pixels (B) and green pixels (G) are formed in parallel. First columnar spacers 10 and second columnar spacers 20 are formed on a first substrate. The distance between the first substrate and a second substrate in a normal state is determined by the first columnar spacers 10. The diameter of a light blocking film corresponding to each first columnar spacer 10 is greater than the diameter of a light blocking film corresponding to each second columnar spacer 20. The first columnar spacer 10 is not formed at a boundary between a green pixel (G) and a red pixel (R) or a boundary between a green pixel (G) and a blue pixel (B). The second columnar spacer 20 is formed at a boundary between pixels irrespective of the pixel color. Thus, appropriate color balance can be attained with ease without having a drop in the luminance.
