pointer to flexible array of structures in other structure

I'm trying to put pointer to flexible array of structures in other
structure. I want to have pointer to array of pixels in screen
structure. Here is mine code, but I think it isn't quite all right:

struct pixel
{
int x;
int y;
int color;
};

struct display
{
pixel *screen;
};

Now I would like to do something like that (to have screen made of 10
pixels):

struct display scr;
scr.screen = (struct pixel*)malloc(10*(sizeof(struct pixel)));
scr.screen[0].x = 10;

and it is working, but what is worrying also
scr.screen[11].x = 10;

or
scr.screen[100].x = 10;

is working. I don't now what is wrong. I'm not sure but I think I'm
making mistake when defining structures. How should I define flexible
array of structures in structure? And how should I point it?

Thanks for help and Merry Xmas,
John
