Problems solved by technology

[0005] However, when forming a scattering structure by this method, it is necessary to go through the steps of first forming a layer made of a resin material on the substrate on the back side, then patterning the resin layer to form fine unevenness, and then Forming the reflective layer on the substrate makes it difficult to suppress the complication of the manufacturing process and the increase in cost

Embodiment 1

[0030] A-1: Structure of LCD Display

[0031] First, refer to figure 1Embodiment 1 in which the present invention is applied to a passive matrix reflective liquid crystal display will be described. As shown in the figure, the structure of this liquid crystal display panel 1a is that the first substrate 10 and the second substrate 20 facing each other are bonded to each other through a sealing material 31, and at the same time, for example, TN (twisted nematic) type or STN (super twisted nematic) Type liquid crystal 32 is enclosed in the area surrounded by both substrates and sealing material 31 . Below, such as figure 1 As shown, with respect to the liquid crystal 32, the side of the first substrate 10 is referred to as "observation side". That is, it means the side where the observer who observes the display image of the liquid crystal display panel 1a is located. On the other hand, with respect to the liquid crystal 32, the side of the second substrate 20 is referred to ...

Embodiment 2

[0063] Below, refer to Figure 10 The structure of the liquid crystal display panel according to Embodiment 2 of the present invention will be described. Figure 10 shown in each section with the above figure 1 The parts common to the liquid crystal display panel 1a of the illustrated embodiment 1 are denoted by the same symbols.

[0064] In the above-mentioned embodiment, the structure shown is that the color filter 23, the light-shielding layer 22, and the cover layer 24 are formed on the surface of the second substrate 20 located on the rear side. On the contrary, in the liquid crystal display screen 1b of this embodiment, if Figure 10 As shown, these elements are provided on the surface of the first substrate 10 on the viewing side.

[0065] That is, on the surface of the first substrate 10 that faces the liquid crystal 32, a light-shielding layer 22 that overlaps the gaps between the sub-pixels 5 and a color filter 23 that is colored with a pigment in one of red, gree...

Abstract

Color filters are disposed over a substrate so as to transmit light of a wavelength corresponding to a specified color, and an inner surface of each color filter is a rough surface having ridges and valleys. Further, pigment particle groups in each of which a plurality of pigment particles are aggregated are dispersed in each color filter.

Description

technical field [0001] The invention relates to a liquid crystal display and an electronic instrument using the liquid crystal display, in particular to a color filter substrate used in a liquid crystal display and a manufacturing method thereof. Background technique [0002] A so-called reflective liquid crystal display generally has a structure in which a reflective layer is provided on a rear substrate among a pair of substrates sandwiching liquid crystal. The basis of this structure is that external light such as sunlight incident on the liquid crystal display screen from the viewing side passes through the liquid crystal from the viewing side substrate to reach the surface of the reflective layer, and is reflected by the surface and then emitted to the viewing side. And, a reflective display is realized by observing the emitted light by a viewer. A reflective LCD panel does not require a light source such as a backlight, so it can achieve low power consumption and thin...
