Abstract
Provided is a liquid crystal display element capable of reducing the decrease in light utilization efficiency caused by the increase in definition. A liquid crystal display element includes: a drive substrate having pixel electrodes having light-reflective properties and arranged in a matrix; a counter substrate arranged opposite to the drive substrate; and a liquid crystal material layer sandwiched between the drive substrate and the counter substrate, in which the pixel electrodes are arranged on a display surface side of the drive substrate in a state of being separated from each other with a slit portion interposed therebetween, an entire surface including surfaces on the pixel electrodes is covered with a first dielectric film formed on the pixel electrodes and a second dielectric film formed in the slit portion, and the second dielectric film has a hollow portion extending along the slit portion.
