Specific implementation mode

With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.Implement below Example is not limited to the scope of the present invention for illustrating the present invention.

The display panel of the present invention, including black matrix (BM), as illustrated in fig. 1 and 2, black matrix includes:First hyaline layer 110 With the second hyaline layer 120.A wherein surface for first hyaline layer 110 is formed with the knot of several continuously distributed positive triangle cones 111 Structure, i.e., the structure that this positive triangle bores 111 must be fine and close, locally flat structure cannot occurs, to avoid light leakage.Second is transparent Layer 120 is formed on the structure of the positive triangle cone 111.The refractive index of first hyaline layer 110 is more than the second hyaline layer 120 Refractive index, and the refractive index of the first hyaline layer 110 is more than the previous layer material that light in display panel is incident on the first hyaline layer 110 Refractive index, to ensure light from device to enter BM to be to enter optically denser medium from optically thinner medium to realize that the negative direction of light is anti- It penetrates.

The black matrix of display panel of the present invention has the special layers structure of positive triangle taper, being capable of edge using positive triangle cone prism The principle for the direction total reflection light of incident ray, so as to make light retrieve utilization, to improve the light extraction of light Rate.And will not make light inside period diffusing reflection and lead to the principle of colour contamination.

The material of first hyaline layer and the second hyaline layer is that (the photoresist refractive index of different materials differs photoresist Sample) or other transparent materials.

The present invention also provides above-mentioned display panel production method, include made on a wherein substrate for display panel it is black Matrix, the black matrix making step are as follows:

Step 1 forms the transparent material of first refractive index on the substrate, and by its surface imprint at continuously distributed Positive triangle cone figure.

Step 2 forms the transparent material of the second refractive index to fill coining pattern on positive triangle cone.

Wherein, the transparent material surface of first refractive index is embossed into positive three using using nanometer embossing in step 1 The figure of pyramid.

In the present embodiment, transparent material is photoresist (being not limited to photoresist).Step 1 specifically includes at this time:

The photoresist of first refractive index is formed on the substrate.

Curing process is carried out to the photoresist of the first refractive index, and in semi-cured state, using nano impression skill The figure that art is bored in its surface coining at continuously distributed positive triangle, is subsequently cured, to fix shape.
