BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field of a liquid crystal device having a microlens on a counter substrate and electronic equipment using the same, and in particular, a microlens is provided on one surface of a projection or transmission type liquid crystal device. This invention belongs to the technical field of a liquid crystal device having an array and electronic equipment using the same.

2. Description of the Related Art Conventional thin film transistors (hereinafter referred to as TFTs)
When a liquid crystal device of an active matrix driving system by driving etc. is used as a light valve in a liquid crystal projector etc., in general, projection light is incident from the side of a counter substrate which is arranged to face the TFT array substrate with a liquid crystal layer in between. To be done. Here, when the projected light is incident on a region for forming a channel formed of an amorphous silicon film or a polysilicon film of the TFT, a photoelectric current is generated in this region due to a photoelectric conversion effect, which deteriorates the transistor characteristics of the TFT. Therefore, in this type of liquid crystal device, it is necessary to surely prevent light from entering the channel forming region.

In order to improve the display contrast and color reproducibility when using this type of liquid crystal device in a so-called normally white mode in which the liquid crystal device is transparent when a voltage is not applied and non-transparent when a voltage is applied. It is necessary to prevent light leakage between the pixel electrode and the data line. This is because there is a non-aligned region of liquid crystal especially between the pixel electrode and the data line, and in this type of liquid crystal device,
It is necessary to cover the non-aligned region of the liquid crystal with a black member having a light absorbing property.

Therefore, in the conventional liquid crystal device, the TF
A metal material such as Cr (chromium) or Al (aluminum) on a counter substrate facing the TFT array substrate on which the T and data lines and the scanning line are provided and facing the TFT, the data line, and the scanning line. A light-shielding layer made of, for example, resin black is added to absorb or reflect light that does not contribute to display.

However, the light-shielding layer is formed in advance with a sufficient size in consideration of the positional deviation between the TFT array substrate and the counter substrate which are bonded to each other by mechanical alignment. Specifically, it has a width larger than the line width of the data lines and the scanning lines formed on the TFT array substrate. Therefore, there has been a problem that the ratio of the pixel area in the display screen of the liquid crystal device, that is, the so-called aperture ratio becomes small and the display screen becomes dark.

Therefore, in order to solve such a problem, of the two substrates constituting the liquid crystal device, the substrate facing the liquid crystal layer of the substrate located on the light source side is provided at a position corresponding to each pixel. A plurality of microlenses are arranged in a matrix, or another transparent plate is provided on the light source side of the liquid crystal device, and a plurality of microlenses are arranged in a position corresponding to each pixel on one surface of the transparent plate. It is proposed that the light emitted from the light source is condensed in each pixel area by each microlens and the display screen is brightened by arranging the light sources in a circular pattern or the like, for example, JP-A-60-165621-16.

However, in recent years, liquid crystal projectors are also required to have high resolution, and the pixel pitch tends to be made finer. Need to increase.

Here, as a method for improving the light utilization efficiency of the microlenses, the characteristics of the microlenses themselves are improved, or the microlenses arranged in a matrix form are connected in a convex shape having a condensing function. It is conceivable to connect the parts with each other or to enlarge the opening area of each pixel.

However, if it is attempted to further increase the aperture area of each pixel in the conventional structure, the width of the light shielding layer is made narrower than the conventional one, and the line widths of the data line and the scanning line are made narrower than the conventional one. However, it is extremely difficult in the manufacturing process of the TFT array substrate to narrow the line width to the extent that the improvement of the light utilization efficiency of the microlenses can be visually discerned.

The present invention has been made in view of the above-mentioned problems, and it is provided with a microlens corresponding to the opening area of each pixel and a light-shielding layer corresponding to each pixel, with respect to a TFT constituting each pixel. An object of the present invention is to provide a liquid crystal device and an electronic apparatus including the liquid crystal device, which can further improve the light utilization efficiency of the microlens even in the case of shielding light and preventing light leakage in the non-aligned region of the liquid crystal. And

[0011]

In order to solve the above-mentioned problems, a liquid crystal device of the present invention comprises a pair of a first substrate and a second substrate between which a liquid crystal is sandwiched, and a plurality of liquid crystals are provided on the first substrate. Data lines, a plurality of scanning lines intersecting the plurality of data lines, a switching element electrically connected to each data line and each scanning line, and electrically connected to each switching element. A plurality of microlenses arranged in a matrix corresponding to each of the pixel electrodes, and a light shielding layer formed between adjacent microlenses on the second substrate. The light-shielding layer is formed so as to overlap with the data line or the scanning line in a plan view, and the width of the light-shielding layer formed corresponding to the adjacent microlens is equal to that of the data line or the scanning line. Thinner than line width The features.

According to the liquid crystal device of the present invention, at least the channel forming region of the switching element provided on the first substrate and the plurality of scanning lines and the plurality of data lines also provided on the first substrate are provided. Are arranged so that the light-shielding layers provided on the second substrate overlap. Therefore, even when light is incident from the second substrate side, the light is reliably prevented from entering the channel forming region of the thin film transistor, and the generation of leak current is suppressed. Further, an opening region of a pixel, which is defined by each scanning line and a data line and is composed of a switching element and a pixel electrode, is defined by a plurality of wirings including a data line or a scanning line provided on the first substrate, and the light shielding layer is provided. Is smaller than the line width of the data line or the scanning line, the size of the opening region can be increased by the light-shielding layer even if a positional deviation occurs during the bonding of the first substrate and the second substrate. Is not affected,
The desired aperture ratio can always be obtained. Further, the width of the light shielding layer is narrower than the line width of the data line or the scanning line, and the opening of the light shielding layer is larger than the conventional one. Therefore, the range in which light is collected by the microlenses provided in correspondence with the aperture area of each pixel is wider than in the conventional case, and the light utilization efficiency is higher than in the conventional case. Here, when the width of the light-shielding layer is made narrower than the line width of the data line or the scanning line, light leakage due to the non-aligned region of the liquid crystal may occur. Since the microlenses can focus light only on a desired and appropriate area, the light leakage does not occur. As described above, according to the liquid crystal device of the present invention, even when light is shielded from the TFTs forming each pixel and light leakage is prevented in the non-aligned region of the liquid crystal, the light utilization efficiency of the microlens is further improved. Can be
Even if the upper and lower substrates are displaced, a desired aperture ratio can be obtained.

In the liquid crystal device of the present invention, liquid crystal is sandwiched between a pair of a first substrate and a second substrate, and a plurality of data lines intersect with the plurality of data lines on the first substrate. A plurality of scanning lines, a switching element electrically connected to each data line and each scanning line, a pixel electrode electrically connected to each switching element, and a capacitance line forming a storage capacitor. A plurality of microlenses arranged in a matrix corresponding to each of the pixel electrodes, and a light shielding layer formed between adjacent microlenses on the second substrate. The layer is formed so as to overlap with the capacitance line when seen in a plan view, and the width of the light-shielding layer formed corresponding to the adjacent microlenses is smaller than the line width of the capacitance line. To do. Also with the above configuration, the range where light is condensed by the microlenses provided corresponding to the aperture areas of the respective pixels becomes wider than in the conventional case, and the light utilization efficiency is improved as compared with the conventional case.

The light-shielding layer has an opening along the light collecting portion of the microlens, a connecting portion between the microlenses, and a non-light collecting portion formed between the connecting portion and the light collecting portion. And a light-shielding portion that covers the According to this configuration, the shape of the opening of the light shielding layer is not the shape along the opening area of each pixel as in the conventional case, but the shape along the condensing portion of the microlens. The utilization efficiency of can be significantly improved compared to the conventional one. Further, since the shape of the light-shielding portion of the light-shielding layer covers the connecting portion between the microlenses and the non-light-collecting portion, it is possible to reliably prevent light from leaking from the non-light-collecting portion between the microlenses. Only the light from the condensing portion of the microlens can be applied to the opening area of each pixel. Therefore, it is possible to irradiate light only on a desired region which is not affected by the non-aligned region of the liquid crystal, and a good display without light leakage is realized.

Further, in the microlens, it is preferable that the respective condensing parts are connected by a condensing connecting part formed in a convex shape.

According to this structure, the microlenses form a so-called microlens array, and the light collecting portions of the respective microlenses are connected by the light collecting and connecting portions formed in a convex shape. Therefore, not only the light incident on the opening area, but also the light entering the outside of the opening area,
Since the light is condensed in the opening region, the light utilization efficiency can be extremely increased.

Further, the second substrate includes a transparent base substrate and a transparent cover member that is mounted on the base substrate and is in contact with the liquid crystal, and the microlens is the cover member of the base substrate. It is preferable that the light shielding layer is formed on the opposite side of the cover member, and the light shielding layer is formed on the contact side of the cover member with the liquid crystal.

According to this structure, the microlens is not formed only by the thermal deformation of the photosensitive material as in the conventional case, but the transparent base substrate forming the second substrate is formed by the subsequent etching process. Since it is formed in the above, the light absorption property is extremely low, and the light utilization efficiency can be sufficiently enhanced as compared with the case where it is formed of a photosensitive material as in the related art. Further, the base substrate does not soften due to temperature rise, and can be used for high energy light. Since the light-shielding layer is formed on the cover member attached to the transparent base substrate, the light-shielding layer and the condensing portion of the microlens can be accurately aligned with each other, and a high-brightness liquid crystal without light leakage can be obtained. Provide a device.

The light shielding layer may be formed on the surface of the first substrate facing the liquid crystal.

According to this structure, since the light shielding layer is formed on the surface of the first substrate facing the liquid crystal, the light shielding layer is formed with high positional accuracy in the opening area of each pixel, and the aperture ratio is improved. It is possible to surely shield light without lowering it.

Electronic equipment of the present invention is characterized by including the above-mentioned liquid crystal device.

According to the electronic equipment of the present invention, since it is provided with the above-mentioned liquid crystal device, there is no leak current and no light leakage, and the liquid crystal can remarkably improve the utilization efficiency of light in the microlens as compared with the conventional liquid crystal. The device enables high-quality display.

The operation and other advantages of the present invention will be apparent from the embodiments described below.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

(Structure of Liquid Crystal Device) First, the entire structure of the liquid crystal device will be described with reference to FIGS.

Further, on the TFT array substrate 1, a capacitance line 31 ′ (storage capacitance electrode) which is a wiring for storage capacitance is formed in parallel with the scanning line 31. Note that the capacitance line 31 ′ may be formed not only in parallel with the scanning line 31 but also under the previous scanning line to form a storage capacitor. Capacitance line 31 '
A capacitance is formed by the pixel electrode 11 and the pixel electrode 11, but this capacitance is omitted in FIG.

Further, on the TFT array substrate 1, a precharge circuit 201 for supplying a precharge signal of a predetermined voltage level to each of the plurality of data lines 35 prior to the image signal.
And a sampling circuit 301 for sampling an image signal and supplying it to each of the plurality of data lines 35, a data line driving circuit 101, and a scanning line driving circuit 104. Note that these circuits are not necessarily provided on the TFT array substrate 1, and the TFT array substrate 1
It may be configured to be provided on a substrate other than the above. Also,
The precharge circuit 201 and the sampling circuit 301 are
Although not essential to the present invention, provision of these circuits is advantageous in eliminating uneven brightness and uneven contrast.

The scanning line driving circuit 104 applies a scanning signal to the scanning line 31 (gate electrode line) in a pulse-wise line-sequential manner at a predetermined timing based on a power source, a reference clock, etc. supplied from an external control circuit.

The data line driving circuit 101 displays images on the six image signal lines 304 in synchronization with the timing at which the scanning line driving circuit 104 applies a scanning signal based on the power supply, the reference clock, etc. supplied from the external control circuit. Signal VID1
When the VID6 is supplied, a sampling circuit drive signal is supplied to each of the six image signal lines 304 to the sampling circuit 301 via the sampling circuit drive signal line 306 so that the data line is electrically connected to each of the six image signal lines 304. .

The precharge circuit 201 is a TFT 202.
Is provided for each data line 35, the precharge signal line 204 is connected to the source electrode of the TFT 202,
The precharge circuit drive signal line 206 is connected to the gate electrode of the TFT 202. Then, a power supply of a predetermined voltage required for writing a precharge signal is supplied from an external power supply via the precharge signal line 204, and each data line 35 is supplied via the precharge circuit drive signal line 206.
The precharge circuit drive signal is supplied from the external control circuit so that the precharge signal is written at a timing preceding the image signal. Precharge circuit 201
Preferably supplies a precharge signal (image supplement signal) corresponding to pixel data of the intermediate gradation level.

The sampling circuit 301 is a TFT 302.
Is provided for each data line 35, and the image signals VID1 to
The image signal line 304 to which the VID6 is supplied is the TFT
The sampling circuit drive signal line 306 is connected to the source electrode of the TFT 302 and the gate electrode of the TFT 302. Then, via the image signal line 304, for example, six parallel image signals VID1 to 6 which are expanded in six phases
When VID6 is input, these image signals VID1 to VID1
Sample VID6. When a sampling circuit drive signal is input from the data line drive circuit 101 via the sampling circuit drive signal line 306, six image signals VID1 to VID6 sampled for each of the six image signal lines 304 are adjacent to each other. Data line 35
It is applied sequentially for each. That is, the data line driving circuit 101 and the sampling circuit 301 are configured to expand the six parallel image signals VID1 to VID6 input from the image signal line 304 into six phases and supply the data signals to the data line 35. .

It should be noted that there is no restriction on the number of phase expansions of the image signal, but when video is displayed, an image signal line is required for each of RGB, so if it is configured by a multiple of 3, the external control circuit is relatively easy. Can be configured to. Needless to say, the image signal lines 304 are required at least for the number of phase expansions of the image signal. In addition, the configuration that performs such phase expansion,
Although not an essential requirement of the present invention, when the dot clock is fast, there is an advantage that the load on the drive transistor of the image signal can be reduced.

In the present embodiment, in particular, the precharge circuit 201 and the sampling circuit 301 have a light-shielding property formed on the counter substrate 2 as shown by the shaded area in FIG. 1 and as shown in FIGS. The data line driving circuit 101 and the scanning line driving circuit 104 are provided on the TFT array substrate 1 at positions facing the peripheral partition 53, and the data line driving circuit 101 and the scanning line driving circuit 104 are provided on a narrow and narrow peripheral portion of the TFT array substrate 1 which does not face the liquid crystal layer 50. Has been.

2 and 3, on the TFT array substrate 1, a display area defined by a plurality of pixel electrodes 11 (that is, a liquid crystal device in which an image is actually displayed by changing the alignment state of the liquid crystal layer 50). A sealing material 52 made of a photo-curable resin as an example of a sealing member that surrounds the liquid crystal layer 50 by bonding both substrates around the area (1) is provided along the display area. A light-blocking peripheral partition 53 is provided between the display area on the counter substrate 2 and the sealing material 52.

When the TFT array substrate 1 is put in a light-shielding case in which an opening is subsequently opened corresponding to the display area, the peripheral partition 53 causes the display area to have an edge of the opening of the case due to a manufacturing error or the like. In order not to be hidden behind the display area or simply to define the display area, for example, a strip having a width of 500 μm or more around the display area so as to allow a shift of several hundreds of μm with respect to the case of the TFT array substrate 1. It is formed from the light shielding material. Such a light-blocking peripheral partition 53 is formed on the counter substrate 2 by sputtering, photolithography, and etching using a metal material such as Cr (chrome), Ni (nickel), and Al (aluminum), for example. Alternatively, it is formed from a material such as resin black in which carbon or Ti (titanium) is dispersed in a photoresist.

In the area outside the sealing material 52, the data line driving circuit 101 and the mounting terminal 1 are arranged along the lower side of the display area.
02 are provided, and the scanning line driving circuits 104 are provided on both sides of the display area along the left and right sides of the display area. The counter substrate 2 having substantially the same contour as the sealing material 52 is fixed to the TFT array substrate 1 by the sealing material 52.

The precharge circuit 201 and the sampling circuit 301 are basically AC drive circuits. Therefore, even if the precharge circuit 201 and the sampling circuit 301 are provided in the portion of the TFT array substrate 1 facing the liquid crystal layer 50 surrounded by the sealing material 52 and sandwiched between the two substrates, the liquid crystal layer 50 by applying a DC voltage is provided. The problem of deterioration does not occur. On the other hand, the data line drive circuit 10
1 and the scanning line driving circuit 104 are provided in the peripheral portion of the TFT array substrate 1 that does not face the liquid crystal layer 50. Therefore, it is possible to prevent the DC voltage component from the data line driving circuit 101 or the scanning line driving circuit 104, which is driven by DC, from being leaked and applied to the liquid crystal layer 50.

In this way, below the peripheral parting line 53,
By providing the precharge circuit 201 and the sampling circuit 301, the scanning line drive circuit 104 and the data line drive circuit 101 can be formed in a peripheral portion of the TFT array substrate 1 with a margin, and in accordance with specific specifications. It becomes easy to design these peripheral circuits. In addition, by providing the precharge circuit 201 and the sampling circuit 301 below the peripheral partition 53, which is a so-called dead space, the effective display area of the liquid crystal device 200 is not reduced, and at the same time, especially the peripheral partition 53 is light-shielding. Therefore, it is not necessary to shield the light incident through the display region from the TFTs 202 and 302 that form the precharge circuit 201 and the sampling circuit 301.

On the other hand, in the counter substrate 2, a region corresponding to the display region of the TFT array substrate 1 in which the pixel electrodes 11 are provided in a matrix shape and surrounded by the peripheral partition 53 as described above is shown in FIG. Is provided with a light shielding layer 23. This light-shielding layer 23 is formed by sputtering, photolithography, and etching using a metal material such as Cr or Ni, similarly to the above-mentioned peripheral parting 53, or is made of resin black or the like in which carbon or Ti is dispersed in a photoresist. Formed from material. Light-shielding layer 23
Is formed of such a material, and the p-Si (polysilicon) layer 32 of the TFT 30 of the TFT array substrate 1 is formed.
The p-Si (polysilicon) layer 32 is provided at a position to cover the p.

Further, the light shielding layer 23 has functions of improving contrast, preventing color mixture of color materials, and the like. That is, the liquid crystal layer 50 has a property that the light distribution state changes by the application of a voltage to the pixel electrode 11, but all the liquid crystal layers 50 in contact with the surface of the image electrode 11 have the same light distribution state. In other words, there is a so-called non-light distribution region in which the desired light distribution state is not reached toward the periphery of the pixel electrode 11. For example,
In the normally white mode in which the pixel electrode 11 is in a non-transmissive state when a voltage is applied to the pixel electrode 11, even if a voltage is applied, a portion through which light is emitted occurs on the peripheral side of the pixel electrode 11. As a result, when the liquid crystal device is viewed in plan as shown in FIG. 2, that is, when viewed from the direction of arrow D in FIG. 3, only the part through which the light passes appears white, so the entire display area should be black. Was not possible, which was a cause of deterioration of image quality.

Therefore, the light-shielding layer 23 is used to cover the non-light distribution portion as described above while ensuring the opening area for image display in each pixel, and to make the contrast uniform and to mix colors. It is being prevented.

(Structure of Microlens) However,
Providing the light-shielding layer 23 with a portion that covers the non-oriented portion means that the opening region is narrowed by that amount, which causes a reduction in the aperture ratio.

Therefore, in the present embodiment, by providing the microlenses 62 at the positions corresponding to the respective opening regions of the light shielding layer 23 on the counter substrate 2, the light emitted from the light source is emitted by the respective microlenses 62. The light is focused on each pixel area, thereby improving the effective aperture ratio of each pixel and brightening the display screen.

In this embodiment, the microlens 6
The position where 2 is formed is, as shown in FIG. 4, which is an enlarged view of the portion indicated by the circle A in FIG. 3, the surface of the base substrate 2a forming the counter substrate 2 on the TFT array substrate side. In the present embodiment, as shown in FIG. 5, which is an enlarged view of the portion indicated by the circle B in FIG. 4, on the front surface side of this base substrate 2a,
A cover glass 2b is attached, and the light shielding layer 23 is formed on the surface of the cover glass 2b on the TFT array substrate 1 side. Then, the microlens 62 and the light shielding layer 23
The positional relationship of is set as shown in FIG. 7, and the microlens 62 is formed at a position where light can be condensed on the opening region of the light shielding layer 23.

In this embodiment, the microlens 6
2 are arranged in a matrix so as to correspond one-to-one to each pixel region, and are configured to increase the effective aperture ratio of all pixels and uniformly increase the brightness of the liquid crystal device. There is.

Further, the microlens 62 of this embodiment is formed not only by thermally deforming the photosensitive material but also by performing an etching process after the deformation, on the base substrate 2a such as neoceram. Since the microlens 62 is formed on the base substrate 2a such as neoceram, the light utilization efficiency is higher than that of the conventional one. Since temperature rise due to absorption and further softening due to temperature rise do not occur, it can be used for high energy light.

Moreover, as described above, in the microlens 62 in this embodiment, as shown in FIG. 6, the microlenses arranged in a matrix are connected by the convex connecting portion 64 having a light-collecting property. Since it is a microlens array, the connection portion 64 also collects light on the opening region, and the light utilization efficiency can be sufficiently increased.

However, the conventional light-shielding layer 23 is similar to that shown in FIG.
As shown in, the width of the portion corresponding to the data line of the TFT array substrate 1 is formed to be equal to or larger than the line width of the data line, and the width of the portion corresponding to the scanning line or the capacitance line is set to the scanning line. Alternatively, because the line width of the capacitance line is the same as or larger than the line width of the capacitance line, when the TFT array substrate 1 and the counter substrate 2 are misaligned during bonding, the opening area is reduced and the light of the microlens 62 is reduced. There was a problem of reducing the utilization efficiency of.

Therefore, in the present embodiment, as shown in FIG. 7, the width of the light shielding layer 23 provided on the counter substrate 2 is made narrower than the line width of the data line or the scanning line or the capacitance line as described above, and the opening is formed. By increasing the aperture ratio of the area,
Even if the TFT array substrate 1 and the counter substrate 2 are displaced from each other, the light utilization efficiency of the microlens 62 is improved as compared with the conventional case.

That is, as is clear from comparison between FIG. 7 showing the configuration of the present embodiment and FIG. 8 showing the conventional configuration, FIG.
In the present embodiment shown in FIG. 8, since the light-shielding layer 23 having a width narrower than that of the data line, the capacitance line, or the scanning line is used, the aperture area of each pixel where the light is condensed by the microlens 62 is different from the conventional one shown in FIG. It can be seen that the area is significantly larger than that of the conventional one, and the area of the microlens 62 that can contribute to the light condensing is wider than before.

This state is shown in FIG. As is clear from FIG. 9, when the light shielding layer 23 having the conventional width shown by the dotted line is used, it is necessary to determine the lens characteristics of the microlens with reference to the opening width W1 of the light shielding layer 23. The light was collected in the range shown by the dotted line in FIG.

However, in the case of the light shielding layer 23 of the present embodiment shown by the solid line in FIG. 9, since the width thereof is narrower than the line width of the data line 31, the opening region width w2 defined by the data line 35 is used as a reference. Since the lens characteristics of the microlens array 62 can be determined as described above, the microlens 62 having a longer focal length than that of the related art can be used, and the light utilization efficiency of the microlens 62 can be significantly higher than that of the related art. .

In this embodiment, the distance between the TFT array substrate 1 and the counter substrate 2 is 4 μm, and the data line 3 is provided as shown in FIG.
When the difference t1 from 5 is set to 1 to 1.3 μm,
It was possible to use a microlens having a diameter of the light collecting portion of 26 μm and a focal length of 80 μm.

By using a microlens, the aperture ratio, which was conventionally about 50%, can be increased to about 70%. However, as in the present embodiment, the light shielding layer 23 of the counter substrate 2 is used.
If the width is set, the aperture ratio can be further increased by about 5%.

At the present stage, the increase rate of the aperture ratio due to the improvement in the pattern design is limited to about 10%, so that the structure of this embodiment is extremely effective for the increase of the aperture ratio. I can do it.

When the light-shielding layer 23 of the counter substrate 2 is formed as in the present embodiment, it may be difficult to prevent light leakage due to the non-aligned region of the liquid crystal, but the lens characteristics of the microlens 62. By appropriately setting, the light can be condensed only in the alignment region of the liquid crystal, so that the light leakage can be surely prevented.

Therefore, in the case of the configuration of this embodiment, it is necessary to set the lens characteristics of the microlens 62 so that the light is condensed only in a predetermined area of the opening area. For example, the focal length of the microlens is set based on the radius of curvature of the microlens, the pixel pitch, the incident angle of light, the F value of the projection lens, the thickness of the cover glass 2b, and the like.

The shape of the light-shielding layer 23 is not limited to the shape shown in FIG. 7, but in the case of a lens in which the length of the connecting portion between the microlenses 62 is minutely formed as shown in FIG. , The opening of the light-shielding layer 23 through the microlens 62
The shape can follow the circular shape. On the other hand, the light-shielding portion of the light-shielding layer 23 also has a shape along the microlens 62. By using such a light-shielding layer 23, it is possible to reliably shield the non-collecting region formed between the microlenses 62 from light. Therefore, a stray light that is not condensed by the microlens 62 does not enter the opening region, and it is possible to reliably suppress the generation of leak current and the like.

(Structure of Liquid Crystal Device) Next, the relationship between the width of the light shielding layer 23 and the line width of the data line, the scanning line or the capacitance line as described above will be described with reference to FIGS. 11 to 14 together with the structure of the liquid crystal device. Will be described in more detail.

The light-shielding layer 23 in this embodiment is shown in FIG.
It is formed in the shape shown by the diagonal lines. Figure 11 is T
FIG. 3 is an enlarged plan view of a part of the display area of the FT array substrate 1, and the light-shielding layer 23 formed on the counter substrate 2 is overlapped and described for easy understanding.
