Abstract

A liquid crystal device includes a substrate, an opposing substrate disposed so as to face the substrate, a liquid crystal layer interposed between the substrate and the opposing substrate, and a plurality of spacers disposed between the substrate and the opposing substrate and having different aspect ratios from each other.

Claims (9)

1. A liquid crystal device, comprising:

a substrate;

an opposing substrate disposed so as to face the substrate;

a liquid crystal layer interposed between the substrate and the opposing substrate;

a touch key structure enabling a variety of information to be input by change of capacitance formed between the opposing substrate and the substrate when a surface of the opposing substrate, which does not face the liquid crystal layer, is pressed;

a first spacer disposed between the substrate and the opposing substrate for maintaining a constant distance between the substrate and the opposing substrate; and

a second spacer disposed on the substrate so as not to be in contact with the opposing substrate, the second spacer having a lower height than that of the first spacer and having a narrower width than that of the first spacer.

2. The liquid crystal device according to claim 1 , further comprising a display region on the substrate including a transmissive region and a reflective region, the first spacer disposed in the transmissive region, the second spacer disposed in the reflective region.

3. An electronic apparatus, comprising the liquid crystal device according to claim 1 .
