Disclosed herein is a liquid crystal display panel in which circumferences of a pair of substrates disposed so as to face each other are stuck at a given distance to each other by a seal material, a liquid crystal inlet is formed in a part of the seal material, and a liquid crystal is sealed in an inner space defined between the substrates paired with each other, the liquid crystal display panel including a resin film being formed on the inner space side of one of the pair of substrates, and an inorganic insulating film being formed on a surface side of the resin film. An area not having the inorganic insulating film being present therein is formed in the liquid crystal panel.

A vertical alignment liquid crystal layer is sealed between a first substrate having a first electrode and a second substrate having a second electrode, each pixel region has a reflective region and a transmissive region, and a gap adjusting section is provided on one of sides of the first substrate and the second substrate which sets a thickness (gap) d of the liquid crystal layer which controls a phase difference of incident light to the liquid crystal layer so that a gap dr in the reflective region is smaller than a gap dt in the transmissive region. An alignment controller which divides alignment of the liquid crystal within a pixel region is provided in the pixel region on at least one of the sides of the first substrate and the second substrate. It is also possible to optimize by changing the gap in red, green, and blue.

A process for manufacturing a liquid crystal panel where a liquid crystal is held between a pair of substrates is characterized by marking a specified figure on one substrate, detecting the specified figure on the one substrate, applying a sealing material according to a predetermined pattern and providing a liquid crystal encapsulation opening in the vicinity of the marking, joining another substrate paired with the one substrate thereto, cutting the joined substrates to obtain a pair of substrates, injecting a liquid crystal material through the liquid crystal encapsulation openings of the pair of substrates thus obtained, and closing the liquid crystal encapsulation openings. According to the invention, a process for manufacturing a liquid crystal panel in which positioning of the liquid crystal encapsulation opening is facilitated in the step of applying the sealing material can thereby be provided.
