Main body groove portions are formed along the longitudinal direction on the surface of a spacer height adjusting layer provided on a margin area of a large-size glass substrate. The cross-sectional area between seal materials between image display areas is increased. An air discharge efficiency from the inside of the image display area between the large-size glass substrates can be enhanced. The air discharge from the inside of the imaged is play area can be further reliably and readily performed. Liquid crystal composition can be readily injected from a liquid crystal injection port into the image display area. The time required to inject the liquid crystal into the image display area can be shortened. The productivity of liquid crystal panels can be enhanced.

Board device and liquid crystal display device

A liquid crystal display device comprises a first substrate, a columnar spacer formed on the first substrate and exhibiting light shielding properties, an alignment film formed to covet at least a part of the columnar spacer, a second substrate arranged to face the first substrate with a predetermined gap provided by the columnar spacer between the first and second substrates, and a liquid crystal material arranged within the gap. The columnar spacer is tapered in the forward direction as viewed from the first substrate in that portion of the columnar spacer which is positioned closest to the second substrate and has the largest diameter portion in the region other than that region of the columnar spacer which is positioned closest to the first substrate.
