Abstract
Abstract A reflection type liquid crystal display apparatus has a liquid cell having an upper substrate having an electrode pattern formed with transparent electrodes, a lower substrate opposed to the upper substrate and having an electrode pattern formed with metallic reflecting electrodes, an orientation film formed on each of the two electrode patterns, and containing liquid crystal put between the upper and lower substrates, and an electronic part connected to the liquid crystal cell and used to drive the liquid crystal cell, wherein each of the metallic reflecting electrodes is a two-layer film composed of Ti and Al alloy and formed on the lower substrate.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
A reflection type liquid crystal display apparatus comprising: a liquid cell having an upper substrate having an electrode pattern formed with transparent electrodes; a lower substrate opposed to said upper substrate and having an electrode pattern formed with metallic reflecting electrodes; an orientation film formed on each of said two electrode patterns; and containing liquid crystal between said upper and lower substrates; and an electronic part connected to said liquid crystal cell and used to drive said liquid crystal cell, wherein each of said metallic reflecting electrodes is a two-layer film composed of Ti and Al alloy and formed on said lower substrate wherein said Al alloy contains at least one of Zr, Ti, and Ta components and the content of said Al alloy component is within 0.1 at % to 5 at %.
Claim 2
Dependent Claim
134 words
A reflection type liquid crystal display apparatus comprising: a liquid cell having an upper substrate having an electrode pattern formed with transparent electrodes; a lower substrate opposed to said upper substrate and having an electrode pattern formed with metallic reflecting electrodes; an orientation film formed on each of said two electrode patterns; and containing liquid crystal between said upper and lower substrates; and an electronic part connected to said liquid crystal cell and used to drive said liquid crystal cell, wherein each of said metallic reflecting electrodes is a two-layer film composed of Ti and Al alloy and formed on said lower substrate wherein said Al alloy contains at least one of Zr, Ti, and Ta components and the content of said Al alloy component is within 0.1 at % to 5 at %.
