[0039] First, a liquid crystal device according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 4 .

[0040] The liquid crystal device of this embodiment is an active matrix liquid crystal device using TFT elements as pixel switching elements. Moreover, as shown in FIG. 3 , it is a transflective liquid crystal device of a so-called multigap type, which includes a TFT array substrate 10 (first substrate), and is arranged opposite to the TFT array substrate 10 and placed in front of the observer. The opposite substrate 20 (second substrate) on the side, the liquid crystal layer 50 sandwiched between the substrates 10, 20, and the reflective electrode 15r provided on the TFT array substrate 10 to reflect light incident from the opposite substrate 20 side , and liquid crystal layer thickness adjustment for making the layer thickness of the liquid crystal layer 50 in the reflective display region R where the reflective electrode 15r exist...

[0075] Next, a second embodiment of the present invention will be described.

[0076] The basic configuration of the liquid crystal device of this embodiment is the same as that of the first embodiment. The difference is that, in the first embodiment, a pair of initial transfer structures are arranged at positions overlapping with the plane of the pixel electrode, but in contrast to this, in this embodiment, a pair of initial transfer structures are arranged at positions not overlapping with the plane of the pixel electrode. Initial transfer construct. Therefore, only this point of difference will be described below.

[0077] For the liquid crystal device of the present embodiment, for example, the liquid crystal device of the form illustrated in FIGS. 5( a ), ( b ), FIGS. The pair of initial transfer structures are arranged in a position not planarly coincident with the pixel electrode 15 , that is, an area outside the so-called display area. Among them, the "display area"...

Abstract

A liquid crystal device includes: a first initial transfer structure configured to form an initial transfer nucleus of the liquid crystal layer on a side of the first substrate facing the liquid crystal layer; and a second initial transfer structure configured to form the initial transfer nucleus at a position corresponding to the first initial transfer structure on a sire of the second substrate facing the liquid crystal layer with the liquid crystal layer interposed therebetween. The invention provides an OCB-mode liquid crystal device capable of performing initial transfer in a short period of time at a low voltage and an electronic apparatus using the same.

Description

technical field [0001] The invention relates to a liquid crystal device and electronic equipment, in particular to a liquid crystal device in OCB (Optically Compensated Bend) mode. Background technique [0002] In the field of liquid crystal devices typified by liquid crystal televisions and the like, in recent years, liquid crystal devices of the OCB mode, which have a fast response speed for the purpose of improving the image quality of moving pictures, have attracted attention. In the OCB mode, it is necessary to meet the requirement that the orientation of the liquid crystal molecules in the initial state becomes a spray alignment arranged in a spray (spray) state between the two substrates, and the orientation of the liquid crystal molecules becomes a bowed state (bend alignment) during the display operation. ). Furthermore, during display operation, high-speed responsiveness is realized by modulating the transmittance according to the degree of curvature of the bend o...
