## Abstract

A modulized display component and a manufacturing method for the same are disclosed in this invention. The display component of this invention is designed according to a modulization concept so that it can be attached to any driving circuit layer. Further, various manufacturing techniques can be used to form the alignment layers and protective layers in order to fabricate a trans-reflective, reflective, or transmissive color displaying component.

## Claims

### Claim 1

A modulized display component, comprising:
a substrate;
an electrode layer formed on a surface of the substrate;
a plurality of wall structures disposed directly on the electrode layer, the wall structures being closed shape structures;
an alignment layer covering the wall structures;
a display medium filled in spaces formed between the wall structures above the alignment layer;
a protective layer formed on the alignment layer and the display medium, the protective layer directly contacting the alignment layer; and
an additional alignment layer disposed between the display medium and the protective layer, wherein the protective layer does not have an alignment feature.

### Claim 2 (depends on 1)

The modulized display component according to claim 1, wherein the substrate is a flexible substrate.

### Claim 3 (depends on 2)

The modulized display component according to claim 2, wherein the appearance of the flexible substrate is a sheet or a film.

### Claim 4 (depends on 1)

The modulized display component according to claim 1, further comprising a color filter layer formed on the surface of the substrate.

### Claim 5 (depends on 1)

The modulized display component according to claim 1, wherein the electrode layer is designed to be a driving electrode for a passive matrix or a segment driving display device, or to be a common electrode layer.

### Claim 6 (depends on 1)

The modulized display component according to claim 1, further comprising an alignment material formed on top of the filled display medium.

### Claim 7

A modulized display component, comprising:
a substrate;
an electrode layer formed on a surface of the substrate;
a plurality of wall structures disposed directly on the electrode layer, the wall structures being closed shape structures, an entire bottom surface of each wall structure contacting and being covered by the electrode layer;
an alignment layer covering the wall structures;
a display medium filled in spaces formed between the wall structures above the alignment layer;
a protective layer formed on the display medium and the alignment layer, the protective layer directly contacting the alignment layer; and
an additional alignment layer disposed between the display medium and the protective layer, wherein the protective layer does not have an alignment feature.

### Claim 8 (depends on 1)

The modulized display component according to claim 1, wherein the protective layer is an air-tight layer.
