Figure 12 is the sectional view for other configuration examples for indicating second substrate SUB2.

Configuration example shown in Figure 12 is clipped in second layer L2 and first layer compared with configuration example shown in Figure 11, in protective layer OC On this point between L1, is different.In this configuration example, second layer L2 is equivalent to protrusion PJ2.Protrusion PJ2 by with colour filter The identical materials of CF4 are formed.That is, protrusion PJ2 is white layer or hyaline layer.The color of protrusion PJ2 and colour filter CF1 and The color of CF2 is different.

Protective layer OC covering second layer L2 (protrusion PJ2), colour filter CF1 and colour filter CF2.First layer L1 is across guarantor Sheath OC and it is opposed with second layer L2.Height TL2 (height TPJ2) is than height TC12 and TC22 high.As a result, second layer L2 with Protective layer OC connects.

In this configuration example, the identical effect of configuration example as shown in figure 3 can be also obtained.

Figure 13 is the vertical view for the configuration example for indicating light shield layer BM (first layer L1), second layer L2 and colour filter CF. This, indicates the vertical view parallel with X-Y plane.

Light shield layer BM forms lattice-shaped in the example in the figures, has part BMX (BMX1, BMX2, BMX3) and part BMY (BMY1, BMY2, BMY3, BMY4).Part BMX intervals arrange on second direction Y, and distinguish on X in a first direction Extend.These parts BMX is Chong Die with scan line G respectively in plan view.Various pieces BMX is formed as on second direction Y With the band-like of substantially certain width.Part BMY intervals arrange on X in a first direction, and respectively on second direction Y Extend.These parts BMY is Chong Die with signal wire S respectively in plan view.Various pieces BMY is formed as on X in a first direction With the band-like of substantially certain width.Light shield layer BM has the opening portion OP divided by part BMX and part BMY.Opening portion OP is configured to rectangular along first direction X and second direction Y.

Colour filter CF is Chong Die with each opening portion OP.In the example in the figures, the colour filter CF of different colours X in a first direction Upper arrangement.Y is configured colour filter CF1 in a second direction between part BMY1 and part BMY2.Colour filter CF2 part BMY2 with Y is configured in a second direction between the BMY3 of part.Colour filter CF3 and colour filter CF4 is between part BMY3 and part BMY4 along Two direction Y are alternately arranged.In the example in the figures, colour filter CF4 is between part BMX1 and part BMX2, colour filter CF3 Between part BMX2 and part BMX3.In one example, the color of colour filter CF1 is red, and the color of colour filter CF2 is green The color of color, colour filter CF3 is blue, and the color of colour filter CF4 is white or transparent.It is however also possible to omit colour filter CF4 And make colour filter CF3 Y configurations in a second direction between part BMY3 and part BMY4.

Second layer L2 is set to as shown in the region of oblique line between the colour filter CF of different colours.That is, the edges second layer L2 Second direction Y settings, it is Chong Die with each section BMY.Second layer L2 is formed as having substantially certain width on X in a first direction It is band-like.In the example in the figures, width of the second layer L2 in a first direction on X is smaller than part BMY, and positioned at the big of part BMY Cause center.In addition, second layer L2 can be arranged a plurality of between colour filter CF, part of it can be bent.

By configuring such second layer L2, the protrusion for having first layer L1 and second layer L2 can be formed.As above Described, the height of protrusion is higher than the height of the colour filter of each color, therefore, it is possible to inhibit the colour filter of adjacent different colours Contact.

Figure 14 is the vertical view for the other configurations example for indicating light shield layer BM, second layer L2 and colour filter CF.

Example is configured shown in Figure 14 compared with configuring example shown in Figure 13, and this point has discontinuously been configured in second layer L2 It is different.Second layer L2 is not formed in the both sides on the first direction X of the opening portion OP1 Chong Die with colour filter CF4.On the other hand, Second layer L2 is formed in the both sides on the first direction X of the opening portion OP2 Chong Die with colour filter CF3.More particularly, the second layer L2 is not set between colour filter CF4 and colour filter CF2 in the BMY3 of part, and set between colour filter CF3 and colour filter CF2. In addition, second layer L2 is not set between colour filter CF4 and colour filter CF1 in the BMY4 of part, and it is set to colour filter CF3 and colour filter Between device CF1.

In the example in the figures, second layer L2 has the length LCF than colour filter CF3 in part BMY3 and BMY4 Big length LL2, and second layer L2 be clipped between colour filter CF3 and colour filter CF2 and colour filter CF3 and colour filter CF1 it Between all areas.

In the case where the colour filter CF of different colours as described above is adjacent, color material is oozed from adjacent colour filter CF sometimes Enter to generate the discoloration etc. of colour filter CF.But in the case where a side of adjacent colour filter CF is white or is transparent, That is, colour filter CF4, with any one adjoining of colour filter CF1, CF2 and CF3 in the case of, color material from colour filter CF4 to other The influence that colour filter CF penetrates into is small.Therefore, between colour filter CF4 and adjacent colour filter CF, it is convenient to omit second layer L2.

Therefore, in this example, effect identical with configuration example shown in Figure 13 can also be obtained.

Figure 15 is the vertical view for the other configurations example for indicating light shield layer BM, second layer L2 and colour filter CF.

Configuration example shown in figure 15 configures the filter of different colours compared with configuring example shown in Figure 13, in Y in a second direction It is different on this point that color device CF and second layer L2 are set to part BMX.That is, the second layer L2 X and second party in a first direction Extend on Y, is set as lattice-shaped.

In the example in the figures, colour filter CF1 is Chong Die with opening portion OP1, and colour filter CF2 is Chong Die with opening portion OP2, colour filter Device CF3 is Chong Die with opening portion OP3.That is, between part BMY1 and part BMY2, the colour filter CF1 and colour filter of different colours (third colour filter) CF3 is adjacent on second direction Y.In addition, between part BMX2 and part BMX3, the colour filter of different colours X is adjacent in a first direction with colour filter CF2 by device CF1.

According to this configuration example, Y is also configured with the colour filter CF of different colours in a second direction other than first direction X In the case of, it can also inhibit the contact of adjacent color filter CF.

As described above, according to the present embodiment, it is capable of providing a kind of reduction that can inhibit to show grade Filter substrate and display device.
