Abstract

A liquid crystal display device includes multiple pixels which are arrayed. Each pixel includes a first substrate, a second substrate, a first electrode formed on an opposing face of the first substrate which faces the second substrate, a second electrode formed on an opposing face of the second substrate which faces the first substrate, a liquid crystal layer which includes liquid crystal molecules, situated between the first electrode and the second electrode, and a planarization layer. The liquid crystal molecules are pretilted. Multiple ridge-and-groove portions are formed at the first electrode. At least the grooves of the first electrode are filled in by the planarization layer.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Japanese Priority Patent Application JP2013-136080 filed with Japan Patent Office on Jun. 28, 2013, the entire content of which is hereby incorporated by reference. technical field [0003] The present disclosure relates to a liquid crystal display device including a liquid crystal display element in which a liquid crystal layer is sealed between a pair of substrates. Background technique [0004] In recent years, liquid crystal display (also referred to as LCD) devices have been widely used as display monitors for liquid crystal television receivers, notebook personal computers, car navigation devices, and the like. These liquid crystal display devices are classified into several display modes (modes) by molecular arrangement (orientation) of liquid crystal molecules contained in a liquid crystal layer sandwiched between substrates. An example of a commonly used display mode is a T...
