A display device that includes a reflective electrode; a transparent electrode; a partition; an EL layer formed over the partition and the transparent electrode; a semi-transmissive electrode formed over the EL layer; and a coloring layer over the semi-transmissive electrode. A light-emitting region is formed to overlap with the transparent electrode, the EL layer, the semi-transmissive electrode, and the coloring layer. A non-light-emitting region is formed to overlap with the transparent electrode, the partition, the EL layer, and the coloring layer. The non-light-emitting region is formed to surround the light-emitting region. The sum of the optical length of the transparent electrode and the optical length of the EL layer is adjusted to fulfil a condition of a microcavity intensifying light of the color of the coloring layer. The optical length of the partition in the non-light-emitting region is adjusted to weaken external light incident through the coloring layer.

A photoelectric conversion device with a novel anti-reflection structure. In the photoelectric conversion device, a front surface of a semiconductor substrate which serves as a light-receiving surface is covered with a group of whiskers (a group of nanowires) so that surface reflection is reduced. In other words, a semiconductor layer which has a front surface where crystals grow so that whiskers are formed is provided on the light-receiving surface side of the semiconductor substrate. The semiconductor layer has a given uneven structure, and thus has effects of reducing reflection on the front surface of the semiconductor substrate and increasing conversion efficiency.

The invention discloses a direct printing method of a low-temperature plasma processed fabric. The method comprises the following steps: firstly, finishing a fabric to be printed by low-temperature plasma processing equipment; fully coating a quaternary ammonium salt solution on the surface to be printed of the fabric by a sizing tool of a first color register in roll coating equipment or printing equipment; then orderly printing color pastes of other color registers on the surface to be printed of the fabric by printing equipment according to patterns designed in advance; and finally fixing, washing and sizing to obtain the finished product. An experiment indicates that compared with that of direct printing of a fabric which is not processed by plasmas, the apparent color yield K/S of direct printing of the low-temperature plasma processed fabric disclosed by the invention is improved by 10%-50%.
