Abstract

A liquid crystal display panel includes: a pair of substrates arranged to be opposite each other to sandwich a liquid crystal layer, an upper electrode in which a plurality of slit-shaped openings are provided in parallel in each of a plurality of subpixels formed in a display region being provided on one of the pair of substrates, a lower electrode being formed on the substrate through the upper electrode and an insulating film, and a shield electrode being formed on the other substrate to face the liquid crystal layer, wherein, when the pitch between adjacent slit-shaped openings is P, and the width of the upper electrode between adjacent slit-shaped openings is L, L/P is in a range of 45% to 55%.

Claims (5)

1. A liquid crystal display panel comprising:

a pair of substrates arranged opposite to each other to sandwich a liquid crystal layer, an upper electrode in which a plurality of slit-shaped openings are provided in parallel in each of a plurality of subpixels formed in a display region being provided on one of the pair of substrates, a lower electrode being formed on the substrate through the upper electrode and an insulating film, and a shield electrode being formed on the other substrate to face the liquid crystal layer,

wherein, when the pitch between adjacent slit-shaped openings is P, and the width of the upper electrode between adjacent slit-shaped openings is L, L/P is in a range of 45% to 55%, and

wherein, when transmittance is T, and a drive voltage which is applied between the upper electrode and the lower electrode is V, an efficiency value E expressed by T 3 /V is equal to or greater than 95% of the maximum value, and the transmittance T is equal to or greater than 98% of the maximum value.

2. The liquid crystal display panel according to claim 1 , wherein the upper electrode is a common electrode.
