Abstract

A light-reflection type liquid crystal display device includes (a) a liquid crystal display panel, (b) a polarizer mounted on the liquid crystal display panel, (c) a light-guide mounted on the polarizer, (d) a resin layer sandwiched between the polarizer and the light-guide for fixing the polarizer and the light-guide to each other, (e) a light-source arranged adjacent to an end of the light-guide for supplying light to the light-guide, and (f) a frame having a bottom and a wall defining an opening which has the same contour as that of the light-guide. The light-guide is positioned relative to the polarizer by being lowered along an inner wall of the frame through the opening onto the polarizer.

Claims (16)

1. A method of fabricating a light-reflection type liquid crystal display device including at least a liquid crystal display panel, a polarizer lying on said liquid crystal display panel, a light-guide lying on said polarizer, and a resin layer sandwiched between said polarizer and said light-guide for fixing said polarizer and said light-guide to each other, comprising the steps of:

(a) fixing said liquid crystal display panel on which said polarizer is mounted, onto a bottom of a frame having an opening which has the same contour as that of said light-guide;

(b) dropping resin onto said polarizer;

(c) lowering said light-guide along an inner wall of said frame through said opening onto said polarizer; and

(d) hardening said resin.

2. A light-reflection type liquid crystal display device comprising:

(a) a liquid crystal display panel;

(b) a polarizer mounted on said liquid crystal display panel;

(c) a light-guide mounted on said polarizer;

(d) a resin layer sandwiched between said polarizer and said light-guide for fixing said polarizer and said light-guide to each other;

(e) a light-source arranged adjacent to an end of said light-guide for supplying light to said light-guide; and

(f) a frame having a bottom and a wall defining an opening which has the same contour as that of said light-guide,

said light-guide being positioned relative to said polarizer by being lowered along an inner wall of said frame through said opening onto said polarizer.

3. The light-reflection type liquid crystal display device as set forth in claim 2 , wherein said opening is larger than a contour of said light-guide by a predetermined length.

4. The light-reflection type liquid crystal display device as set forth in claim 3 , wherein said predetermined length is equal to a tolerance allowable when said liquid crystal display panel and said light-guide are positioned relative to each other.

5. The light-reflection type liquid crystal display device as set forth in claim 2 , wherein said liquid crystal display panel is comprised of two substrates adhered to each other through adhesive, said frame is formed at a bottom thereof with an opening, and an inner edge of said opening is located more outwardly than said adhesive.
