Embodiment approach 1

[0059] Next, Embodiment 1 of a substrate and a liquid crystal display device in the present invention will be described with reference to the drawings.

[0060] figure 1 It is a cross-sectional view showing the liquid crystal display device in this embodiment. figure 2 yes means figure 1 A cross-sectional view of a common substrate in a liquid crystal display device. image 3 is a plan view showing the same common substrate. Figure 4 yes image 3 magnified top view of .

[0061] The liquid crystal display device in this embodiment is a reflective simple matrix liquid crystal display device. In the figure, reference numeral 1 denotes a first substrate, 2 denotes a reflective film, and 3 denotes a display area.

[0062] In this liquid crystal display device, basically, a liquid crystal layer 45 made of STN (super-twisted nematic) liquid crystal or the like is sandwiched between a pair of substrates 1, 31 made of glass substrates or the like.

[0063] Such as figure 1...

Embodiment approach 2

[0093] Next, Embodiment 2 of the substrate and the liquid crystal display device in the present invention will be described with reference to the drawings.

[0094] In this embodiment, with Figure 1 to Figure 4 The difference between the illustrated first embodiment lies in the arrangement of the electrode 7 with respect to the reflective film 2 . The same symbols are used for other constituent elements, and explanations thereof are omitted.

[0095] Figure 5 It is a plan view showing the common substrate in the liquid crystal display device of the present embodiment.

[0096] In the common substrate 47 of this embodiment, the configuration of the reflective film 2 relative to the underlying substrate 1 is the same as image 3 , Figure 4 The shown implementation 1 is slightly different, as Figure 5 As shown, in each of the electrodes 7, 7, the lead wirings 6', 6' completely overlap the reflective film 2.

[0097] In short, the portions of the electrodes 7, 7 that do ...

Embodiment approach 3

[0104] Next, Embodiment 3 of the substrate and the liquid crystal display device in the present invention will be described with reference to the drawings.

[0105] In this embodiment, with Figure 1 to Figure 4 The difference between the illustrated first embodiment lies in the arrangement of the reflective film 2 with respect to the underlying substrate 1 . The same symbols are used for other constituent elements, and explanations thereof are omitted.

[0106] Image 6 It is a plan view showing the common substrate in the liquid crystal display device of the present embodiment.

[0107] In the common substrate 47 of this embodiment, it is set that the reflective film 2 has approximately the same area as the underlying substrate 1, such as Image 6 As shown, each electrode 7, 7 completely overlaps with the reflective film 2.

[0108] That is, it is set so that there is no portion that does not overlap the reflective film 2 among the electrodes 7, 7 .

[0109] Moreover, t...

Abstract

The invention relates to a liquid crystal display device. A conductive reflection film 2, covering at least a display region 3, is provided on a first board 1 of a pair of boards 1 and 31, having electrodes 7 and 7 of at least prescribed patterns disposed oppositely via a liquid crystal layer 45 and on the surface of the liquid crystal layer 45 side. On the first board 1, the ratio S2 / S1 of an area S1 of the film 2 to an area S2 of the part not superposed with the film 2 of the electrode 7 is set to 0.001 or less.

Description

technical field [0001] The invention relates to a substrate, a liquid crystal display device and an electronic instrument, in particular to a substrate having a conductive film such as a reflective film or an electromagnetic shielding film and electrodes, a liquid crystal display device and an electronic instrument. Background technique [0002] Figure 12 An example of a simple matrix drive type liquid crystal display device is shown, Figure 12 The structure of the liquid crystal display device 200 shown is: a pair of transparent rectangular substrates 220, 221, with a sealing material 222 sandwiched between them, forming a whole. [0003] exist Figure 12 In the illustrated structure, substrate 220 is generally referred to as an upper substrate, and substrate 221 is generally referred to as a lower substrate. Such as Figure 12 As shown, when the substrate 221 is at the front and the substrate 220 is at the back, when the two are erected horizontally, the substrate 220 is...
